Danny Trevathan is a little small for the NFL at outside linebacker. He would likely fill a role as an outside linebacker, in the case that the six-game suspension of D.J. Williams for performance enhancing drugs is upheld.
Despite his size, however, Trevathan shined in a talent-loaded SEC last season. He led the SEC with 143 total tackles (76 solo tackles), 12 tackles for a loss, and three sacks. He also had four picks, broke up five passes and forced five fumbles.
As you can see, he had a knack for the ball and he was a playmaker on the defensive side of the ball. Again, this wasn't in some mid-major conference, this was in the SEC, where two teams in the conference (Alabama and LSU), Nos. 1 and 2 respectively, played for the national championship.
If you can get past his smaller size at 6'0" and 237 pounds with a 32.5" wingspan, you have a top prospect with major upside. Trevathan could potentially be one of the biggest steals of the draft in the 6th round, especially if he proves to be a worthy replacement of D.J. Williams in 2012.
