UCLA senior linebacker
Height, weight: 6-foot-4, 245 pounds
Previous rank: No. 4
His case: Though his tackle numbers have been fairly low, this stud linebacker has been a terror behind the line of scrimmage. He has all four of his sacks in his last three games, and he's tied for fourth in the nation with 2 tackles per loss per game (9 solo, 2 assisted). It's not all Hundley in Los Angeles, that's for sure.
What we said before the season: Barr was a running back and wideout his first two years at UCLA before moving to linebacker, a position he hadn't played since he was 13 years old. Last year, he recorded 13.5 sacks, second-most in the nation. You might remember him from the sack that ended Matt Barkley's career.
