80% of the QBs you mentioned's teams have made the playoffs. 40% to conference championships and 20% to a super bowl. 60% have won a playoff game.
I would gladly "over pay" for a QB that helps bring success, like Alex or Colin rather than stomp my feet, close my ears, and say "but he's not good enough to win a Super Bowl" (like we really know that).
