The "Win Window"
I was riffing earlier about the concept of something called a "win window." What is it? I'm not sure yet.
Here's how I came up with the thought. My FOOL ballclub was an expansion team. I took a strategy pretty early on that would be a team that would be able to compete for a title from the outset pretty much. And short of a successful first half of that first season, we've been evading it ever since. A 3rd place finish, a 5th place and 4th place finish respectively have been the story of the day for us over the past three years. I've felt like we're always just a player or two away. I recently flubbed up a free agent signing that was supposed to be the masterstroke in an otherwise brilliant off-season. Now, I'm looking at things and despite all I gave up (prospects for acquiring two pitchers to bolster my rotation and bullpen) I'm still just "one or two players" away. I've realized in other online leagues too, that the problem is largely related to the inorganic nature of the online league trade market. You only have a few teams at any one time that are considered actually bothering to make any deals. Then you have inactive owners who sit on good to great talent. Anyway, the point of this is, there has to be a way to ineffectively measure how much a particular player will "contribute" to a team that's looking to add some value to the ballclub. I think VORP might be the easiest way to do it. What are the thoughts on this? Last edited by Young Drachma : 07-30-2008 at 07:13 PM. |

Isn't that what "Win Shares" was supposed to be calculated to try to measure? |

Win Shares does this:
Win shares are intended to represent player value (what they were responsible for) rather than player ability (what the player's true skill level is). Whereas my "Win Window" is a team statistic aimed at evaluating a team's talent to determine whether the team really is a contender or a pretender. It's a fictional statistics for fictional games, as I doubt you could use it in a real life context given the variables that apply to the real world that don't apply to the fictional world.

Hmm.. well theoretically if you believe that "Win Shares" is a definition of how many wins a player theoretically adds to a team, you should be able to work together and figure out how many "Win Shares" that were on the entire team for a cumulative "Win Shares" that theoretically should be pretty close to how many wins the actual team did win. So then you can try to take that a step further, and figure out a way to forecast the "Win Shares" for each individual for a forecasted Win Shares of some sort. This is somewhat difficult as Win Shares is designed to be a reporting statistic and not a predictive statistic however. (Similar to your suggestion of VORP however). Perhaps you could trend a player's Win Share and then have comparison win shares for similar players of age and ability and create a forecasted win shares that way. Then add all of the forecasted Win shares for every individual on the team to create a total team forecasted win shares. Then it is a case of determining if your team's entire total forecasted win shares ends up being in the range of where you feel a contending team should be or not to determine if they are in their win window... This is probably alot of work and may not even be accurate however without testing or research, but it is the only suggestion I could think of. |

Well, you're certainly giving me stuff to think about. I'm going to generate some data in-game and see what I can mess around with. I never do download the CSVs, but I think I will so I can take a look at stuff more detailed, since I'm super curious about some things. |

However... (and I could be wrong), couldn't using Win Shares to evaluate the teams "Win Window" be a bit incestuous? After all, isn't the number of total win shares assigned to a teams players is simply 3x the number of wins the team earned. The only reason for this to be different is roundoff error, or players who spent part of a season with one team and part with your team.

Has a ton of theories and such, mostly about real baseball that I could, were I feeling ambitious come up with theories for fake baseball (and by proxy, could be used for real baseball) and statistical methods that measure a player's value. They're not even THAT complicated when he breaks it all down. It's just taking the time to 1) invest in developing a measure and 2) creating a calculator for people to use it and actually find value in it. |

I've noticed that winning teams minimize the number of negative VORP guys they have. I haven't figured out what sort of index I want to create yet, mostly because I don't feel like hand calculating a lot of stats, but...that's the thing I'm seeing universally as I sim in my test league./

I just ran a test in OOTP9 using an MLB standard league.
The VOCL for an MLB league is lower than a fictional league. Doesn't surprise me, because the league VOCL is going to really be determined by the talent level that you're playing against, etc. So we need to figure out how to get the VOCL modifier for each league. That 450 number in the test equation I ran was based on fictional online leagues that I'd done some research in. After looking at some MLB numbers, I think the number needs to come down to about 400. That's about the threshold for a 100 win team in the majors. Now there are going to be playoff teams and thus, champions with a VOCL in the 300s. It's just inevitable because divisional play waters things down considerably. But the measure is still effective. So I've decided to tweak things a bit and create a new statistic that feeds off the VOCL, because it makes more sense to me and is a better measure of what this whole stat was supposed to be. The VOCL modifier is going to be lowered to 400. Here are the factors for our new stat calculating the win window. To determine a team's Win Window, you calculate the VOCL + Win Differential (W - L) / Number of Games in the season = Win Window |

Looking at what you are trying to do here with "VOCL" to compute how close someone is to a "win window", I think you were going on the correct path in understanding how a lower VOCL can win a championship in MLB play. I think that is mostly due to the higher percentage chance of getting into the post season.
In MLB, you have 8 out of 30 teams or roughly 27% of them make the postseason, but your fictional online league that you used only 2 of 16 teams make the post season or roughly 12-13%. With the randomness in both baseball in general as well as OOTP, even the worst team in all of baseball is going to beat the best team in all of baseball on average at least once or twice in a 10 game span. That means the more rounds that are inserted into the playoffs, the more likely you will have a team "overachieve" or pull off an upset. It is probably far more likely that a 2 team playoff that uses 100+ games to decide whom those two teams are will see a better team as the league champion than an 8 team playoff system due to that. So that makes the required VOCL level needed to possibly win the championship different based on how easy it is to make the playoffs. I would wager even if you changed your fictional league test that you did to include more teams in playoffs, it would have the effect of lowering the average VOCL of the league champions despite the Win differential or number of games in the season remaining fairly constant. |

Well I used FOBL too. That league has playoffs similar to MLB.
And then I used an MLB league, as well, to do testing. That's why I lowered the threshold. I looked at all of the playoff teams and the numbers were relatively consistent. But what I was trying to do was concoct what makes a "better" team versus not. That said, you make a good point that playoffs make the threshold lower and because of that, it'd be wiser to consider lowering the number. But I didn't want to make the number so low that it was important to focus on JUST making the playoffs, but maybe I ought to consider that, since well...if you make the playoffs, you can win and that's what we're trying to measure. Right now, it measures a team that's pretty much title worthy at the level of 90+ wins or so. But using the VOCL as the championship level threshold and the win window as the measure for how close your team is to being "in the hunt" of things, makes it work pretty well. Thanks for checking it out.

Yeah, I don't think my argument is necessarily as true in other sports such as say Hockey or Basketball which includes a fairly large amount of teams. In those sports it just seems less likely to have massive upsets round after round to a championship. In baseball though there just seems to me to be a much higher chance of a "worse" team beating a "better" team due to hot streaks, randomness or who knows what though. I haven't honestly done research on this, and may just be assuming things incorrectly, but I wonder since football and baseball went to a wildcard format, what the win% is for the team with the better record in the playoffs for Hockey, Football, Basketball and Baseball. |

Yeah, I think this is totally a baseball thing. I don't think it'd work in other sports, because the threshold is so low to make the playoffs and the barriers to entry for bad teams winning it all is..well...not as easy as it is for a hot baseball team to get going.

On the same subject (of the chance of upsets in the playoffs), I did a web search and came across this interesting article that I think pretty much supports the point being made.. The more teams in the playoffs, the harder it is for the best team to win, even when a much more superior team than others.

I think that I'd add "especially in baseball."
I don't know what about the game that lends itself to that, but...it seems like that'd be the case far more in baseball than in other sports, where playoffs actually make some sense. It could be the excessively long regular season.

I think it is because of the game and not the length of the season or anything else.
In this game, if you do things at a very low percentage of success, you are considered great. If you get a hit 33% of the time, you are one of the best contact hitters in the game. If you throw out a base stealer 30% of the time, you have a good arm at catcher If you hit a home run 15% of the time, you might end up in the hall of fame. That doesn't carry over to other sports, where you have to be a 75% free throw shooter, or you need to hit at least 60% of your shots from the court in basketball.. or in football where you need to complete at least 50-60% of your passes to keep a QB job, or connect on 85% or more of your field goal attempts. The difference between hitting .320 and .270 for a season is what? 1 hit a week, or maybe 5 hits a month difference between two players? I think when dealing with such small differences meaning such a great difference of perception, it just lends to a game where upsets are more frequent.. I could be way off base though as I don't really have much statistical proof here on this, just trying to figure it out in my head. |

Win Window calculator
Here's a spreadsheet that will calculate VOCL and Win Window for teams. WW is still an ugly stat, but I dunno what to do it to make it "prettier" yet. Or what to add to it to make it look better.
It seems to be effective, though and that's all I care about. It's based on FOOL at the moment, but you can totally adapt it for another league.

I think you are on the right track as well. I personally feel that the formula may be a better predictor if it could say take the past two years of results at a 25% and 35% weight each for the VORP's and take a predicted batting and pitching VORP for the remaining 40%. Here are the following reasons I beleive this would be need to be factored in.

Predicted VORP wouldn't really work since PECOTA isn't really in the game, it's just projected as the season goes along, which doesn't help for something like this. It would, however, make it a stat that indeed has some real world value. W00t. Awesome.
It's not really intended to be a predictive statistic, it's meant to be an assessment tool of where you were with what you had and to tell you cereris paribus how your team would be able to perform the following year, were you to add more VORP and subsequently more wins. That said, I like the idea of weighting the past two years of results. Maybe even going to three years, going 15, 25, 60 for them in order from 2 yrs ago to present.

I've created a stat here called the Right Track Index (RTI). RTI takes a team's VOCL over a three year period, weighting the most recent year higher, the next year less and the 3rd year less than that (55-30-15) to evaluate whether a team is on the 'right track' or not. The higher the number, the more 'on track' they are. Our numbers are skewed in the sense that Valdosta has won three titles in a row and are clearly a juggernaut for the ages. But that said... Here's the numbers for the most recent 3 seasons of FOOL. Code:
RTI tells us that at the end of 1972, Valdosta is clearly on a track all their own. This measure would be coupled with a RTI Chg that would reflect from year to year how much a team gained or lost in RTI, to really be able to track their performance over a particular period of time. For me personally, it tells me that even though I know my team is getting out of a crazy situation, having just had our first two winning seasons in franchise history in the last two years, that we've still got a lot of work to do to be amongst the contenders like Colorado, Rio Grande, Brooklyn and Valdosta, all teams that have won titles in recent years. I'm attached a spreadsheet that calculates this, along with Retained and Predictive Value. To refresh those are: Quote:

DC, The last three seasons probably aren't the best to try to test this with index with simply because there has been very little change at the top of the standings over the past three seasons.
What would be really interesting is to measure the 1965-1969 time period perhaps, as there was a different champion each year, and you saw the start of the Valdosta dynasty during this time. It would be interesting to see what happened post St.Louis being folded and watch the growth of Colorado, Valdosta, Ann Arbor, and a few others during this time and see what your index tells us about these teams. |

Good call. I'll take a look at that and see what we have.
