N/S Curious QB Question (draft related)

Would you think of Cam Newton, Kellen Moore, Andy Dalton, or Ricky Stanzi as being legit pro prospects or "system" QB's?

I know the LSU fans probably don't have a lot of love for Newton, but I think I kinda like him as a player and think he could be a legit pro.

Perhaps as a late round "homer" pick, what about Adam Weber (from Minnesota)? ;-)
