But the defense was sensational, with a big fourth-down stop, a handful of sacks and most importantly five takeaways, including a game-clinching 29-yard interception returned for a touchdown by Sam Madison.
"We got lucky at some point," said offensive tackle Todd Wade. "We have to thank the defense for winning the game for us. I'm tired of having to thank the defense for winning the game for us."
This was a difficult battle for the Dolphins, who are now 3-0 on the road and were able to maintain their half-game lead in the AFC East following New England's victory over the Giants.
The Dolphins looked like they were going to dominate this game after Madison recovered a Fred Taylor on the first series of the game and they cashed in the turnover with a Ricky Williams 13-yard touchdown run.
But the offense continued to self-destruct while Jacksonville mounted enough offense to tie the game at 10-10.
The Dolphins then stopped the Jaguars after they had a first-and-goal from the 10 and Madison later clinched the victory with his second pick of the game.
