The college football season is upon us and after Week 1 (save the Monday night Louisville-Ole Miss matchup) this much is clear: There is no surefire consensus on the top quarterback in this class.

That doesn't mean they aren't lights-out talents, just that it's anyone's guess how this QB class shakes out.
