So if (likely) Dart chooses Kiffen, that's fine. Doesn't mean he's going to be a Heisman at UM, he could be pretty average to a dud for all we know of course. Hall is a proven starter at BYU that is getting better and better, why would you be upset as a fan if that's your guy starting next year? I have no idea if Connover is as good as his HS film shows him to be on the college level, he'll get a chance to get on the field and prove it someday.
Just side note, Dart did not look more impressive then Jaren Hall in that USC game. So current comparisons taken into account, Jaren would be much better for wins next year then Dart. If you are talking long term potential then that's an entirely different debate, perhaps Jackson does have much better upside. We'll see how it turns out.
