Coming off an impressive road win over the Texans, the Jets played their Week 2 home opener against their AFC East rival, the New England Patriots. In the week prior to the game, first-year Jets head coach Rex Ryan placed a phone message to all Jets season ticket holders asking them to "make it miserable for (Tom) Brady and company," following up on his comments during the off-season that he would not "kiss Bill Belichick's Super Bowl rings." He told the Jets fans that "the Patriots had a better head coach and a better quarterback," but that the game would decide "who has a better team." Meanwhile, Jets safety Kerry Rhodes said the Jets intended on not just winning, but "embarrassing" the Patriots in the game, while nose tackle Kris Jenkins called it the Jets' version of the Super Bowl; the Jets had not defeated the Patriots at home since 2000. On the first drive of the game, without an injured Wes Welker, the Patriots drove to the Jets' 36-yard line before having to punt. The Jets' first play from scrimmage was a strip-sack of rookie quarterback Mark Sanchez by defensive lineman Mike Wright; Sanchez recovered the fumble at the Jets' 3-yard line. On 4th-and-24, the Jets punted back to their own 49-yard line; the Patriots could not capitalize on the field position and went three-and-out. However, Jets running back Leon Washington fumbled on the next play; cornerback Leigh Bodden recovered it at the Jets' 17-yard line. Two holding penalties would push the Patriots back to the Jets' 37-yard line, setting up a 45-yard Stephen Gostkowski field goal to give the Patriots a 3-0 lead. Following a Jets three-and-out, the Patriots moved to their own 41-yard line before Jets cornerback Darrelle Revis intercepted a pass intended for Randy Moss at the Jets' 16-yard line. The Jets offense would continue to struggle, however, going three-and-out again to end the first quarter. The Patriots began the second quarter with a 9-play, 53-yard drive, one that stalled at the Jets' 7-yard line; the Patriots settled for another Stephen Gostkowski field goal, extending their lead to 6-0. The Jets would pick up their initial first down of the game on their next possession, going 52 yards on 10 plays before a Jay Feely 33-yard field goal cut the Patriots' lead in half. Starting from their own 10-yard line after a holding penalty on Sam Aiken on the kickoff, the Patriots took nearly six minutes off the clock, reaching the Jets' 11-yard line before two incomplete passes by Brady prevented the Patriots scoring their first touchdown of the game. Instead, Gostkowski kicked his third field goal of the day to increase the Patriots' lead to 9-3 going into halftime. Receiving the opening kickoff of the second half due to their deferral of the opening coin toss, the Jets took the lead in barely a minute. Following a 43-yard kick return by Washington, Sanchez hit wide receiver Jerricho Cotchery for 45 yards and a play later connected with tight end Dustin Keller on a 9-yard touchdown pass. The 10-9 lead was the first for the Jets over the Patriots at home since 2001. After a Patriots three-and-out, punter Chris Hanson's 30-yard punt gave the Jets the ball at the Patriots' 45-yard line. From the Patriots' 6-yard line, Sanchez appeared to throw a touchdown pass to Chansi Stuckey, but the catch was overturned after the Patriots challenged. Two plays later, Feely hit his second field goal of the day to give the Jets a 13-9 lead.The Patriots' ensuing possession reached the Jets' 35-yard line on a third down, but back-to-back delay of game penalties on Tom Brady, an incomplete pass, and a face-mask penalty on Moss on the punt backed the Patriots up to their own 40-yard line. However, Hanson's subsequent attempt was better than the first, nullified by the penalty, and the Jets began their next drive from their own 15-yard line. On a 14-play, 63-yard drive that spanned into the fourth quarter, the Jets extended their lead to 16-9 on a 39-yard Feely field goal. The Patriots
