I'll be investigating the effects of fatigue over the next the next few days as well, but I can say that fatigue certainly does have an effect on Blocking, Tackling, GI, and Technique. Perhaps the influence of fatigue is too low, but it certainly has an effect. I'm trying to remember when this was introduced. When I pulled out ratings into a separate rating distribution file I added fatigue to pretty much every calculation that uses ratings. Now ratings and fatigue are combined most times that ratings are referenced they are calculated with fatigue.
In my investigation in fatigue, I plan on looking at a couple of different things.
1. What is the influence on fatigue on a particular play.
2. What are the average values of fatigue across the game.
As for DB, Redhawk and I will revisit these once again, and you are correct, Str/Tkl is too high in DB, the other factors (GI, ATH, SPEED) are certainly the most valuable. STR and TKL and HANDS all play significant roles, but in far fewer situations (after catches and for interceptions). Thanks for the heads up. I'll adjust these now and I'll see if I can write a script that actually tests the value of each attribute as it is seen in a play.
