Yeah, after those three is Cam Newton and Matt Schaub at 4 and 5 (Surprising no one), and then at 6 and 7 is Peyton and Brady, which is interesting.
Even more interesting to me is the top 5 QB's in improving their YPA from non-play action to play action.
RGIII +6.8
Ryan Tannehill +4.5
Cam Newton +4.4
Peyton Manning +4.0
Andrew Luck +4.0
(Next 5 are Cassel, Bradford, Rodgers, Fitzpatrick, Sanchez). Odd company for Greater Manning in mine eyes.
