Well they could have lost 5 straight Super Bowls.
And they could've won all eight.
Their biggest margin of loss was vs Philly last year when they lost by 8. That's one TD and a 2 point conversion. They led that game in the 4th Quarter. The other two they lost were to the Giants. They led one in the 3rd Q and the other in the 4th Q. They lost one by 3 and one by 4.
Anyone who thinks the Pats have been a fluke had better find a new hobby.
They were leading both games vs the Giants very late in the 4th quarter, inside the two minute warning
The Eagles game last year, the Eagles took the lead late but the Patriots were in great position for Brady down 5 with the ball. Then Brady was stripped, the first time they touched him all night, and the Eagles went up 8 with only like 40 seconds left.
In all three losses the lost the lead at
0:35, Giants ended perfect season after miraculous catch by David Tyree. Pats also dropped an easy pick on the game winning drive
0:55, Giants win after Brady & Welker fail to connect on wide open reception that would have put the game away. The Giants then drive like 98 years aided by another incredible reception by Mario Manningham
2:21, Eagles win late, aided somewhat by the league unofficially changing the "reception rules" before the SB, although they didn't make it official until this season. Then the uncharacteristic Brady late turnover
PS: No excuses, the Giants and the Eagles won those games and that's that, I'm just pointing out that their losses were also all "a game of inches". There are bad calls and missed calls in every game, and then there are a handful of plays that could have changed the outcome of every game.
At the end of the day, you are what you are, and the Patriots are 5-3 in the SB during this amazing run
