A torn ACL forced Henderson to miss the 2005 season, after redshirting as a true freshman in 2004. Once he got back on the field in 2006, he was one of the most active linebackers in the country. As a redshirt sophomore, he had 114 tackles, 6.5 for loss, one sack, and two interceptions. He was amazing as a junior, finishing the year with 133 tackles, 11 for loss, a sack and a pick on his way to All America and All ACC honors.
Henderson is an excellent athlete with very good speed. He has very good change of direction skills, accelerates quickly, and has the speed to close on the ball carrier in a hurry. He has decent size and is not afraid to sort through traffic to stop the run among the big boys. He is aggressive moving forward and lays a lick when he gets to the ball carrier.
Henderson is lean and could stand to bulk up a little more. He also is not as good in coverage as his talent suggests. He is a little hesitant to react to pass plays. Perhaps a little more time on the field will help in this area, as he has the skills to be a standout in this area. He has also had some durability issues during his career. He tore his ACL in 2005, and had some knee and back problems this season.
Henderson has the talent to be a tackle machine on the weakside or potentially inside in a 3-4. His older brother E.J. played for Maryland and is currently with the Vikings. He could potentially be a second rounder just like his brother.
