Both have led their teams to unprecedented success, put up unprecedented statistics, and are hands-down the two best of their generation. Due to the NFL's scheduling, the Patriots and Colts play almost every year (as long as they finish the same place in divisional standings.) Three epic playoff battles, a back-and-forth crowning of the NFL's best by public opinion. Although Brady and Manning don't technically play against each other (since offense plays against defense), do they have the most celebrated rivalry in NFL history? Can you think of a pair of quarterbacks whose head-to-head games were followed as closely, who were compared so frequently, and who's teams were as good? A lot of great QBs have played in the same generation (Montana, Elway, Marino) but didn't go head to head very often.
