I mean all other things about teams being equal, he's top 10 already right?
If you had completely equal teams and were picking a QB to win the game for you, he's on that list in the top 10 IMO.
Peyton, Brady, Brees, Rodgers...that's your top 4 in some order probably.
Then you've got a guy like Matt Ryan, Eli, Roethlisberger.
Filling out 8, 9, and 10 you could make the argument at the end of the season that it would have been the three rookies, Luck, Wilson, and RGIII of course RGIII's injury changes things a bit (or a lot).
