Pass Defense %
 

So... what the crap does this stat mean now? I used to have no idea, but hoped my guys would get over 20%... now, I'm lost again, as players are way over 80%. Have I missed a discussion about this?

{sigh}

Ummm, I know what it literally MEANS, just not what it translates to statistic wise.

In 2K4, for instance, I don't think I ever saw over 30% in that statistic, ever. Now, I see over 90%. I'm not sure how the stat is calculated or what it represents.

From looking at individual games, it appears that games where there are 0 defenses and 0 catches, the CB gets 82.5% for that game. 0 defenses with 2 catches yielded a 37.5%. For the season, he had 17 defenses, 24 caught, 302 plays, and a 90.4%. Just not sure where the % comes from now (wasn't sure on 2k4 either)

Ah. Some folks here derived the formula for FOF2K4, and I'd imagine could do so for this version at some point. I may begin to take a crack this evening.

If I get an easy chance, I'll work on it today. It's usually not too tough to back out. I think it's centered on a value around 80.

(edit - right, 82.5, that's what I meant)

I looked at it quickly and didn't test my theory extensively, but it seemed like it might have been a fairly simple formula (which is now escaping my mind.) I'll look at it tonight if no one else does before then.

'm not sure if it helps any, but here was the formula for 2k4:

20+(50*passes defended + 100*interceptions - 25*passes caught)/pass plays

All I know is in all the experimenting I did on defensive gameplanning I could do nothing to make this number better or worse. An all pass coverage defense only managed to make my run defense terrible.

An initial formula to use for PDPct is

(825 – {{13.5*Caug}*100/PPly})/10 when Ints = 0 and Defn = 0

Any calculation that has {} around it needs to be rounded down to the nearest whole number.


Example player one: 0 Ints, 0 Defn, 1 Caug, 39 PPly

{13.5 * Caug} = {13.5} = 13
(825 – {{13.5*Caug}*100/PPly})/10 = (825 – {13*100/39})/10 = (825-33)/10 = 79.2

Example player two: 0 Ints, 0 Defn, 2 Caug, 39 PPly

{13.5 * Caug} = {27.0} = 27
(825 – {{13.5*Caug}*100/PPly})/10 = (825 – {27*100/39})/10 = (825-69)/10 = 75.6


This formula is just my best guess. I haven't tested the interception part or the pass defense part of the equation. Each caught pass subtracts about 135/PPly from the baseline of 82.5. Each interception looks to add around 500/PPly and each pass defended looks to add around 220/PPly to 250/PPly. For the passes caught part I believe it to be fairly close from my limited testing.

I don't understand why numbers are thrown in there like 825 or 13.5.... why it isn't a more basic formula. This seems more abstract than the QB Rating. Is this actually used anywhere, or did Jim just make it up?
