|While Jadeveon Clowney garners most of the attention and may be the No. 1 overall pick, Barr could be the second-best defensive prospect in the draft. Barr was an outside linebacker for UCLA and will likely line up as an edge rusher on the line of scrimmage or outside linebacker in a 3-4 scheme in the pros. He is extremely athletic and has a quick first step off the snap. While he can use his quickness to blow by offensive tackles, he also has a strong upper body and can bull-rush a lineman to get to the quarterback. He is a physical specimen and regarded as being a vicious tackler, exploding into the ball carrier. He possesses the ideal frame for an edge rusher, using his strong, long arms to reach the quarterback or bat down passes. Despite possessing immense talent and being projected as a top-10 pick, Barr is also extremely raw and still has a lot to learn. He spent his first two years at UCLA as a fullback before making the switch to outside linebacker. He sometimes gets fooled by play fakes and can overcommit. His reaction time also needs some work, but it isn't a major concern for most NFL teams as they believe it will come around with more practice and experience. In his first season playing defense in 2012, Barr had team highs of 13 1/2 sacks and 21 1/2 tackles for loss while totaling 83 tackles in being named to the All-American second team. He was a first-team All-American in 2013 after finishing with 10 sacks, 20 tackles for loss, five forced fumbles, four fumble recoveries and 62 total tackles. Many scouts believe Barr's ceiling is very high and he'll be an impact player in the NFL for years to come.
