First of all, I'll say this again; Patriots fans don't really know what a bad quarterback performance looks like, as we haven't really seen one in several years. The number one job for the quarterback is to protect the football. After that, any big plays and above-average yardage per pass is a bonus. A bad quarterbacking performance is marked by frequent turnovers.
Brady is smart. He knows when the offense is not clicking. He knows when the defense has momentum and has them figured out. That's when you start to see him hesitating and making the lowest-risk throws possible. In a game like Sunday, it's easy for someone to look really bad in a game where the stakes were so high. Truth is, 90% of quarterbacks would have finished that game with 3 INTS; yes, they would have slung the ball for a few nice gains and highlight reel plays, but they wouldn't have won the game.
That said, the problem wasn't Brady's performance on on the field on Sunday, despite all of the media's obsession with him being "soft." Brady is not soft and was not soft. The problem was the preparation by the Patriots, with Brady included. After the game, Deion Branch said he expected the Jets to play man coverage. Really? So, in all their years as pros, the Patriots couldn't adjust to a zone coverage, and they've never seen anything like the defense they saw there? That's what's disappointing, because that is exactly why Belichick and Brady should give their teams the advantage. They've seen it all and should not be surprised by any type of defense.
The Patriots came down the field on the first two positions with some pretty great playcalling. They proved to the Jets that they can drive on them (although they didn't score) using a completely different gameplan from the 45-3 game. It was working to perfection. After that, they relied too much on overthinking the game and believing they needed to outfox the Jets in order to move the ball. Truth is, this was a very talented offense that should have scored 24+ points (let's be honest, they really scored 14) and moved the ball decently against any defensive formation. I chalk most of this up to a lack of preparation, lack of adjustments, and trying to be too smart in a game that would have been better suited to getting the ball to players in the flat and letting them win the quickness battles for consistent 6-8 yard gains.
