Tom Brady as a whole is an abomination, but I think you mean aberration.
Which is true, considering how well they were running the ball. I do think Fitz had a great game (after the INTs) and was one of the reasons for the victory, but there were many reasons for it, luck being one of them.
I actually don't think the PI call on Nelson in the end zone was that bad of a call. The guy clearly was preventing him from getting to the ball with his back turned. Nelson could have certainly had the chance to break it up. Not the best call, but certainly not the worst. Was it really worse than the end zone PI call in the "Just give it to 'em" game in New England? Now THAT was the worst.
