cosign,
play on AA with the cpu running game set at the Heisman level
and lower your running backs ability, line blocks, break tackles sliders. which is what Ive done.
I had to, cause my last game I had 259 yards on 25 carries and 5 td's. thats 10.36yards a carry.
I enjoyed smashing my oppnent though, cause the game before that Duke beat me down something like 52 to 7.
