In know order I'd put the following QB's ahead of him when everyone is healthy
Tom Brady, Peyton Manning, Donovan McNabb, Tony Romo, Jay Cutler, Brett Favre, Matt Hasselbeck, Drew Brees, Eli Manning, Ben Roethlisberger, Carson Palmer, Phillip Rivers, and maybe Kurt Warner right now.
That makes Aaron Rodgers a top 15 QB right now. I kind of rate him and Jason Campbell out very similar.
By this time next year if he improves, I'll probably move him ahead of the likes of Matt Hasselbeck and Kurt Warner.
Again just my opinion and I think this is very good for a first year QB.
This year though, he's been a top 10 QB, but I'm not one to be fast to jump the gun and "crown" him so to speak. See Ryan Grant as an example.
