for me it was December 2007. The Patriots had worked their way back from 6-5 and were at 9-5 when the Steelers came to town. A win and the Patriots would clinch the #2 seed for the 2nd straight year, not a bad accomplishment for Pete Carroll in his 1st year replacing the immortal Bill Parcells. The Patriots had it won. They led 21-13, less than 2 minutes remaining and with the ball at midfield. How nice 10-5 would be, the magic of 1996 was back. Then...for reasons known only to God himself, Drew Bledsoe decides to throw it to a linebacker....... the rest is history. we lose in OT. finish at #3. lose 7-6 at Pittsburgh when Hall of Famer gets the ball stripped by Vrabel. That was my worst regular season loss as a Patriots fan because it was such a waste, and so stupid. Any more nominations?
