for 1 game, in their prime, i would take Manning, Montana, Unitas, Favre, Elway, Marino, Staubach, Steve Young, Starr, and maybe even Kurt Warner - over Brady
dont know enough of how Baugh, Graham, Luckman, Van Brocklin, etc all played
Brady was in the perfect system for too long - hell Troy Aikman was probably better, maybe even Ken Anderson (the least appreciated very good QB)
