College schemes are very simple...hence hard to evaluate QBs if they have "It" unless they have played in a pro-style offense like in LSU (Burrows, Tua etc). Josh was hard to evaluate because he was a 1-read guy at Wyoming. There will be QBs with the "It" factor but may be having a noodle arm like Trent Edwards...Translating them into NFL players is also very hard...except for exceptions like Purdy, Brady etc.
