If we really wanted some game planning/depth chart manipulation - a stamina of 20 would be equal to 20% playing time in the game. No reason that for some player attributes they can't reflect what you get out of a player. Just adjust the numbers so that more players are at 80-90% for stamina. Same for what bigzeke said about durability. Give durability attributes of 90 - 99% and have their health drop for the next start by the value under 100%.

final stats for that game, zero sacks, and he ran for aver 5 yrds per carry.  On the fipside, I gave up 3 sacks and and only ran for 3 yrds per carry.  I know the style you play can affect this but I went with a cons style the firt half, because my OL/DL was better and I didnt need to blitz, the 2nd I mixed it up and played some agg. defense thinking that his OL would be tired and not able to pick up on the blitzes, but that didnt work either.  Sometimes I think I have this game figured out, then all of a sudden things you were doing dont work.  Hope the new update gets here quick and takes the random out of the game.
