Eh, 2K4 for me. People also ignore the fact that cpu QB play was completely broken in 2K5, they rarely ever scrambled and consistently threw into heavy coverage. QB ratings were meaningless in that regard. I had no desire to use dumbed down defensive ratings as a fix.
I'm definitely not saying o-line play doesn't need improvement because it obviously does. I do think the game is finally moving in the right direction though and hopefully the important issues can be resolved. (3-4 defense for one, though this hasn't been done right in any football game)
