No, Peyton Manning RUNS THE OFFENSE. He is the primary play caller for the Colts since his rookie season. His value is not even quantifiable, because he does things that don't show up on stat sheets. Brady does what BB tells him to. He has a better offense and a comfy offensive line on a yearly basis.
I agree with your Sox optimism, but take off the rose-colored glasses. Brady is a step down from Manning.
To everyone saying he was elite before 2007, then that's your opinion. He was significantly better after getting Welker, Moss and Stallworth (who wasn't elite, but above-average at the time).
