Tough question when you exclude who they're throwing too/the team around them because a guy like Aaron Rodgers can excel without a great o-line while Peyton/Brady would struggle. I guess I have to go with Rodgers
My pick would be Drew Brees, I think very highly of him and would take him over any other QB in this league.
If I could only have him for one year, probably Geno Smith, that way I'm assured a high draft pick the following season to get my QB of the future.
Peyton Manning is great if we want to get our hopes high right before a classic chokejob when it matters most. I've seen that movie too many times now to pretend I haven't. Not the GOAT. Not even top 5. Aaron Rodgers is the answer in 2014.
