Of course any given Sunday, but I don't know about fewer good QBs in his time. Since it's superbowl wins you have to include the NFC too. Favre, Brees, A-A-Ron, Cry Me a Rivers, Manning, the other Manning, Big Ben, Gannon, Kurt Warner, Thigpen, Romo, Matty Ice, Palmer, Cam before he broke in half, Andrew Luck, and lots of other "well if they have a great team around them then maybe..." QBs.
