A lot of those things could be fixed. NCAA 14 had a bug where the penalty sliders actually effected gameplay more than the actual gameplay sliders. If your linebackers are doing crazy ****, it was likely because your coverage slider was mad high. DB and coverage play, especially by the AI was dramatically altered by the combination of your gameplay sliders and the penalty sliders.
There were good slider sets that tightened up gameplay pretty **** good after like...two years when someone figured out the bug.
Now, they've modded NCAA14 so much, they've made a completely new game that is pretty **** good. Once they found the backdoor and got into the guts of the game and tinkered with it.
(they did this for Madden, too, but then EA hired the guy who found the backdoor to mod and closed it up)
