I have been tweaking this so much, let me get the figures for you. This may take some time though. I know I started with what I would believe the true weights and heights were for college players in division 1. In my opinion I believe many are very large and strong but not as intellegent as pro players. I made the OL and DL between 295 - 340 lbs. LB ,TE 245 - 265, RB 210 - 265 ,WR 150-225 ,DB 180-210, QB 210-250, K,P 160-210 . Any lineman over 300lbs had a strength of 99 and was edited to be a bit weaker than a lineman that was 290lbs. anyway you get the idea. Let take the OL , I used JD's editor 1.7 and globally randomly distrubuted the weight for the OL and for every player in the league to between 295-340. The distribute was set at default 50. Then went to the speed of the player for OL 65-85 and distributed these numbers globally and so on. I think you just got to find what you think a player should be rated on your own. I just kept tweaking the numbers and found the best results. I played many many exibition games and then continued to tweak the agility of the players and blocking avoidance and so on. I then worked on tweaking the constraint file. This is a very long process there is my NCAA league file uploaded at Mykals website. The contraint files posted there are not accurate to this date, I use a new one. I have made all RB's agility distributed between 80-99 and increased the speed of the DB and LB plus 7. The DL and LB catching has also been increased 7. Any way you have some idea. You have to get familiar with his editor so you can acheive your goal.
