1. You unequivocally said Rodgers is the best, you didn't ask anyone to pick a QB and build an offense around him.
B. Since you want to play what-if relative to building an offensive unit, I give you...Matty Ice; Sam Bradford; Phillip Rivers (yeah, I think he's a tool, but he's got mad skills); Matt Schaub; Drew Brees & Roethlisgoober (on the old side, but both still have good years remaining).
Again, not a Rodgers-hater, not even close. Dude is talented and has a ring.
In my opinion he's not "the best".
"The best" active QBs, regardless of age, are Brady, Manning, Brees, Roethlisgoober, and
Tebow.
