Brees is short and does not have highest top tier arm strength. Those factors alone kept him out of the first round. He benefits from playing at least 9 games a year in a dome and at least 3 more in summer conditions All that said he is truly a remarkable player and deservedly a certain hall of famer. Rodgers is short as well, listed 6'2 which means he may be 6'1. Interestlngly 2 of the top 5 in today's game lack prototypical size.
