My thoughts on the Run Game
Blocking should depend on weight, ratings, formation, and play calling. Aggressive blocking and pancake blocks need a nerf. The O-line, FB, TE(s), and WR(s) should tire faster, and their effectiveness at RBK’ing and PBK’ing should decrease when aggressive blocking is enabled. STR, AGI, ACC, COD, RBK, RBP, RBF, PBK, PBP, PBF, LBK, and IBL should decrease more rapidly because you’re spamming run plays, and every attribute your RB(s) use should drop drastically when running frequently. The D-line should have a better chance based on changes in O-line ratings versus D-line ratings and your defensive play calling. The O-line should tire faster, and their ratings should drop more quickly than the D-line unless the defense settings are also on aggressive. Don’t destroy the run game. Make players have to sub out their starting lineups because the wear-and-tear system alters ratings fairly. Balance is key!
