He had pretty good production in three years at Arizona State (228 tackles, seven sacks, four forced fumbles, one interception). Has very good size for the position and can hold up against bigger blockers and is strong enough to take down larger backs.
Has good pre-snap instincts and likes to jump snap counts and explode into the backfield. He loves to hit and plays with good lower-body explosion. He drives through tackles to finish off ball carriers.
He is a very intense player and does not shy away from contact, he plays with a very high motor. Scrapes well through traffic and uses athleticism and quickness to get around blockers while keeping eyes on ball carrier.
He is instinctive in most aspects of the position and maintains gap responsibilities and doesn't often bite on play action.
He is one of the more intimidating inside linebacker prospects in recent memory and plays with a mean streak, and his intense playing style has drawn comparisons to Ray Lewis.
He is versatile enough to play in multiple schemes in the NFL, and has a reasonably high ceiling if he can keep his head on straight and maintain his conditioning.
That is the good, now the bad. His combine workouts were terrible (5.09-40, 8'8" broad and 30" vertical).
His pro day workouts were not much better either. He only benched 225 16 times which is low for a linebacker of his size. He ran again on March 30 and posted a 4.80, and he was down to 245 pounds.
He has been labeled a head-case that loses control, and he has received penalties on the field for losing control.
With all that said, he is a good football player that needs a coach to keep him focused. This is where Dennis Allen comes into play. He will help get the most out of this young man and I think the Raiders will end up with one of the biggest steals in the draft.
