From the Tuck Rule, Adam Vinatieri, Malcolm Bulter's INT, to the Falcons blowing a 25 point lead, all of their SB victories were solely based on luck & opportunities IMO. Even though Brady is a talented QB, all of their SB victories could've gone either way, just like the regular season/playoffs as well. Matt Cassel lead them to a 11-5 record, yet they still missed the playoffs. And on any given week, the Patriots either win or lose, depending on what happens during the game. Finally, the bottom line is that they don't make costly mistakes as often as other teams. They also have discipline, except for AB, & even though they cheat/are favored by the refs here & there, who else is surprised that they never had an "off year", yet? Even the best of teams have an off year or two.
