Jacksonville becomes the sixth team Babin has played for in the last eight years. He was originally drafted by Houston in the first round (27th overall) of the 2004 draft out of Western Michigan.
The Jaguars need help from a pass-rushing defensive end. Jacksonville has just 13 sacks this year, tied with Oakland for low in the NFL
His style of play could change that.
"I'm a high motor, I'm an intense guy," he said. "I like to play physical and from what the coaches said, that's their brand of football. Hit them in the mouth. I think I will fit in just fine."
Jaguars starting defensive end Jeremy Mincey said Babin is a welcome addition.
"It's only smart and wise to bring in a guy like that, a top pass rusher who can get this defense to where it needs to be," Mincey said. "He has drive, determination and won't back down to anyone. He's just another weapon for our defense. It's all upside with having him here."
There's only one Jaguars player older than Babin — veteran center Brad Meester, 35. Babin feels his presence can help lift a defense that currently ranks 31st in yards allowed per game and 29th in points allowed per game.
"I think that's the line of thinking here," Babin said. "They know how I play. They know I get after quarterbacks and it's one of those things that's contagious.
"One guy starts doing it and then two guys, four guys, then eight guys. I think that's what they're hoping for, and that's what we're going to give them."
