I won't say Peyton is the greatest ever. Frankly, I don't think any QB of the last 10-15 years anyway should be ranked as the best ever without a big asterisk. These guys have been overprotected and not subjected to the wear and tear their predecessors endured. I do think Peyton has been the best of the last quarter century career wise. Brady has played on better teams, but it was really never a question in my mind who was the better QB. Marino was the best young (first 2-3 years) QB of my lifetime- his 1984 is the greatest single season in that span in my opinion. But he plateaued early in his career. Everyone wants to say Brady is the greatest because of the rings, but if that's your criterion you have to go with Graham.
