I've found that the running and passing protection works better if you up them to 15 and reduce the CPU's awareness down to 85.
I've busted an 80 yard run with LT up the gut from a draw with those modifications. You can make it to the outside without LBC and the CPU will make the occasional mistake concerning the deep ball.
I just got powered by Oakland in the 4th quarter with those settings.
I was winning 21-3 with less than four minutes to go and then they get on a 22-3 scoring run.
Final 27-25 Dallas
Sorry that I don't have stats.
It was a hell of a game though.
