Wilson is the most effective runner on that list, but he also has a “career” (three year) QB rating of nearly 100. You don’t learn to stay in the pocket you don’t win on the big stage....
On the other hand if you want a pocket passer, don't pick a guy who's instinct is to take the ball and run on every play and tell him to stand in the pocket and go through his progressions instead. It just doesn't work.
Said another way, nobody tries to tells Tom Brady or Drew Brees to run around and try to scramble for first downs on most plays. Because they know it won't work. So why do they tell people like Vick or RGIII to play like Brady or Brees and expect it to work?
