"But the beauty of Bill Belichick’s team is no matter how grim it might seem, the game usually goes the Patriots’ way. Super Bowls against the Rams (20-17), Panthers (32-29), Eagles (24-21), Seahawks (28-24) and Falcons (34-28 overtime) were all decided late. The five wins in the biggest game of the year have come by a total of 19 points (the Pats also lost two by a combined seven points).

It’s not an accident. We’re not talking about luck."
