OP blitzes & no fatigue for Defensive players is not realistic

Its not fair one player runs blitz plays that cant be stopped by the cpu all game and just sits on a user player  who doesnt have to play defense . So you basically have to play the computer all game on hiesman while they just chill on defemse and only play offense.. no person can blitz all game and never get tired its common sense !!!!

please add defensive fatigue to players blitzing all game
