"It's a bad feeling, obviously," Potter said. "It puts our team in a bad situation there. It's not the one play that cost us the game."
Potter said he had trouble hearing the snap count because thousands of Patriots fans scoped up tickets and helped give Jacksonville its biggest home crowd since 2004.
"It was really loud, which you don't usually expect at home," Potter said.
Coach Mike Mularkey, though, blamed the officials for failing to recognize and penalize New England for yelling out cadence during a hard shift.
"That was disappointing because that was brought up to the officials before the game," Mularkey said. "That was addressed. We practiced it. We practiced it the whole week with those guys shifting with the cadence. ... Obviously they didn't call it and we jumped. Very frustrating."
Regardless, the Jaguars got the ball back after the Patriots failed to run out the clock.
Henne connected with Toney Clemons on fourth down with 22 seconds remaining and then Jordan Shipley for an 18-yard gain that put them at the New England 12. But Chung intercepted Henne's final pass, essentially a jump ball to the middle of the end zone.
"A win is a win, but we know we've got to play better no matter what," Patriots safety Devin McCourty said. "It's better to come out here when you're not at your best and get a win. I think this team really understands it's all about us. We've got to play our best each week. It's disappointing knowing that we didn't play as good as we could."
New England avoided consecutive losses in December for the first time since 2002.
The Pats got some help, too.
The Jaguars had the ball inside New England's 25 seven times, but came away with a touchdown and three field goals.
And not scoring touchdowns against the league's most prolific offense is hardly a formula for success.
"We had them on their heels for a while," Jaguars defensive end Jeremy Mincey said. "They just capitalized, got a few interceptions and a few first downs on us. We held their scoring average down, which is good, and held them to a lot of field goals, which was excellent. It still wasn't enough."
