These CPU challenges offer a reasonable test for EA slider settings since the challenges offer the same starting conditions every time you play through them. The teams change names but the opponent OVR's and starting conditions are always the same.
I've kept track of my scores and some stats and bottom line, my 92 OVR team is getting the same results as my 84 OVR team. Some times I chew clock and some times I try to get the highest score possible. Either way, 92 OVR is not much different from 84 OVR.
The most obvious change in sliders was when a CPU HB with 83 SPD and 64 break tackle, broke a full stop-double-team-tackle at the 5 yard line and ran 95 yards for a TD against a 97 SPD, 99ACC safety.
I'm not saying that what appears to be slider changes is good or bad. Just curious if anyone else has seen similar results.
