I think the two slider tweaks I would like to see is player speed differential (can't remember the exact name) and CPU run defense. Right now the differential is 60 and I end up getting run down by players that have 5-7 points speed lower. Speed should be more important than it current is.

That and with the run defense at 70, the CPU just instantly jumps anything that is a run. I understand trying to make the CPU competitive but when it's twice as easy to complete short passes as it is for a running team to pick up yards, you limit the playcalling quite a bit.
