On Slow?
I've played a couple on Normal with 45 and it helped slightly.
Also, is there any chance it could be the Accel Clock?
The last 2 games i was at Normal/45, one with 12min/20sec, and one with 15/14 and was seeing multiple blown coverages and fast tightends.
The game I'm playing now is Normal/45 with 15min/12sec and it feels more balanced with the linebacker to tight end speed, and the defensive play overall.
EDIT: It's like with less time at the line of scrimmage, the CPU isn't making as many big plays, and CPU defense is playing tighter. Averaging more 5-6 yd per play, than 8-10. Just a theory though.
And these are with the All-Pro
