When I was going through looking for old Madden scouting screenshots I also came across some old NCAA screenshots and saw something that I think would fit really well into to Madden on a multitude of levels and that's the SPARQ score.
You can see it in the top right and for those that are unaware SPARQ stands for
Speed
Power
Agility
Reaction and
Quickness. It's essentially an attempt to quantify athleticism into a single metric. For more info you can
go here. Also, the site
3-Sigma Athlete has created a variation of this called pSPARQ (position specific SPARQ) based on combine and pro-day data that gives players a rating based on their specific position. They also provide a z-score (number of standard deviations a player is above or below the NFL average) and NFL percentile which is essentially the same but shows where the player ranks among peers based on percentage i.e. 85th percentile means he ranks in the top 15% in the league.
Okay, so how does it fit in Madden?
When it comes to incoming rookies, instead of receiving a "combine grade" at the combine, you would first receive a perceived SPARQ score at the beginning of the year. One of the things that bugs me about scouting is that you're given zero info in regards to a players physical traits prior to the combine and this would aim to remedy that. Once you reach the combine you'd receive a players actual SPARQ score based off of their combine numbers as well as a Team Ranking and NFL Percentile. The team ranking would show you where the player ranked compared to the players at his position on your current roster while the NFL percentile would show you where they rank based on the entire league at their position. If they included Pro Days as well it could allow for some variation where a players score could get better as well. For veteran players, it would essentially replace the Physical rating and be sortable through the view roster screen.
Now where they could take this to the next level is by allowing the user to customize the formula to their own specific preferences by both overall and by specific positions. So let's just say the formula is made up of Speed, Acceleration, Agility, Jumping, and Strength and the base scale weighs each attribute equally or 20%. If you coveted speed receivers you could adjust the rating scale to weigh speed more heavily and receivers with good speed would rate higher while slower receivers would grade out much lower. This would be able to be adjusted unique to each position. This would help users not only in the draft but also in trading and free agency at quickly and easily identifying the physical player types that they covet while also weeding ones that they don't want to even consider.
