Hmmmm, not a bad question. Even the best QB will be awful if the front line is awful. I can only speculate as to how Eli Manning would do.
What I do know is the talent that Jackson dark displayed at Ole Miss is just super. He is extremely accurate. Yes I am biased that being said I am trying to look at this from an outsiders point of view.
The only thing that would worry me would be his mental ability to play in the NFL. What happened to talented quarterback so far that came from Ole Miss and just lost it mentally in the NFL: Chad Kelly and Matt Carell.
