A look at a player who gave his team a significant boost in Week 2.
Allen couldn't break into the starting lineup unless there were injuries. He was a heck of a special-teams player, though. So the Dolphins took what they could get and kept him around.
But the Dolphins made a surprise decision right before the season started. They named Allen a starting cornerback. The move seemed to reflect badly on incumbent starter Sean Smith more than it was considered a story of perseverance for Allen.
By now, you probably know Allen had the greatest game of his disappointing career Sunday. He intercepted Brett Favre twice in the second half to help the Dolphins win 14-10 in the Metrodome.
Jason Allen had a bigger game than Jared Allen. Jason Allen was credited with 11 tackles and three passes defensed.
Miami coach Tony Sparano revealed Monday that no defensive player graded out higher than Allen did against Minnesota.
Allen has bounced around from cornerback to safety to nickelback and special-teams ace and never seemed at home. Sparano said assigning him one job has turned out well.
"He's got outstanding athleticism and sometimes that can get you caught in trying to get him to do too many things," Sparano said. "So from our end we needed to back off of that and we needed to say 'OK, this is what we're going to ask this guy to do.' It's what we've done, and the kid has really grown, I think, as a player."
