I suppose I'm in the camp of folks who aren't taking this especially hard.
It's frustrating and disappointing, to be sure, and it would have been magical to win it. But, as Belichick always says and others have pointed out, the game was won and lost on 2 or 3 plays, any of which could have gone either way. I think it just goes to show that sometimes sports can be borderline random, and only our perception and post hoc bias transform it into a coherent narrative.
Manning led an incredible drive. Manningham made an incredible catch. Pierre-Paul is incredible. The Giants are an incredible team. But if an uncovered Welker catches a catchable ball, the Patriots win the game. I don't believe that happened for any particular reason, or that it means that the Giants are inarguably better than the Patriots -- it's just the nature of athletic competition and the arbitrariness of sport. Just as Sterling Moore happened to make a perfect play at a perfect moment against the Ravens, the perfect plays and moments went for the Giants last night.
Overall, I'm sorry the Patriots will have to live with this loss, particularly Kraft (who seemed devastated) and Welker (who I hope will be able to move on). I'm happy for the Giants' organization, especially the Mara family, who have been doing good for the NFL and the New York area for decades.
Hopefully we'll be back next year, with a better team and a better outcome.
Edit: And as someone said elsewhere, this wasn't the '07 juggernaut, 30 seconds from perfection with a 4 point lead. This was a flawed 13-3 team that wouldn't have been in the Super Bowl if not for a Sterling Moore deflection. It was an agonizingly close loss to a worthy opponent. Sometimes you just have to tip your cap, drink some good liquor, and get back on the horse.
Many thanks for this reality check, D ... as for me, I'm consoled by looking forward to what a substantial cap space and a few key picks will do to put the Pats back in play for next season.
