Um, no. He wins us superbowls. As in, he doesn't do it every year, but he's still done it 3 of the past 6 years. 2 years without a superbowl title does not end a dynasty and they certainly don't put those superbowl championships in the not-so-recent past. The Pats were a first down away from nabbing their 4th in 6 years.
