might i suggest payton manning.
won superbowls with 2 different teams, despite a severe neck injury that likely would have sidelined 99% of others, and i say him because he didn't have all that flashy footwork, and i didnt think he was surrounded every season with exceptional talent on both sides of the ball -- including mediocre coaching -- yet still produced qualtiy results, often from bad field position...much like Elway
obviously Brady if our only metric is playoff wins.
