This hurts as much as any loss I can remember. The bottomline is, without Brady's vapor lock mistake to start the game, the Patriots probably win; the Giants might not even score in the first half. Without Brady's ridiculous heave with the expectation that his CRIPPLED TE will make a play, the Patriots might put together a constructive drive that puts them well ahead in the 2nd half. I don't know whether Brady is clutch or not, and yes he did have two spectacular drives tonight, but let's be honest: he did **** the bed when it really mattered tonight. Those errors and the Welker drop are huge, team or not.
As for what happened on the last drive, who cares. There was next to no chance they were going to pull it out.
We could also point to Belichick's challenge of the Manningham catch, but at that point things were out of control.
