it's 'ok'. I mean, it's entertaining, but in no way can you predict the play of your OL....or anyone else on your team/opposing team.
there are times that no matter what you call on offense or defense, the computer will have it's way with you. I like playing close games, and for it to be a bit hard (ie no 'money' plays to run 20 times a game). But, there are times when it's obvious the only reason it's a 'competitive' game is because of dumbass shit.
