Manning is the sexy choice; Son of NFLer Archie, the #1 overall pick, from a big time college program, with as much fanfare as possible coming into the draft. In the pros he's been coddled as much as any player ever, he's been gifted with a hall of fame nucleus of supplementing players to play with and he's played much of his games in the friendly confines of a stadium, with no wind and a steady 72 degrees weather pattern.
Meanwhile, Brady was some lowly 6th rounder who has played outdoors, in the northeast, in the elements, with a supporting cast of characters in his career that none of us can even name.
