I agree except for Flacco. He's only marginally better than Wilson IMO. That's why I go more on the eye test and individual accomplishments. For this reason, I think Rodgers is the best QB in the NFL right now. Admittedly, he didn't have the best game yesterday, but the Packers screwed that up in more ways than one. To be clear, I find Wilson to be a pretty good QB, but as you said, I don't think he's in the Manning, Brady, Rodgers class. In fact, as great as Brady is, he had a lot of help for his 3 SB's too, but that has to be true, otherwise you don't win 3 SB's.
My personal thought is that if you put Wilson on any other team last year they wouldn't have won the SB. Again, Wilson is great, but he's not the main attraction that takes them to 2 SB's (and has won 1) in Seattle. That goes to the defense as a unit, and Marshawn Lynch IMO.
But anyway, you know Wilson is doing his job well when he throws 4 INT's, and at the end of the game Joe Buck is calling him a "winner."
