A great athlete, Ronnell Lewis' draft stock is based more on ability and potential than production. In his final season at Oklahoma, Lewis produced just 5.5 sacks and 59 tackles.
Because of his small size, Lewis is best suited for a 3-4 defense, and could play either inside or outside linebacker in the 3-4.
WalterFootball.com writes about Lewis:
Lewis played really very well this year, and he excelled at defensive end. His ability to rush the passer off the edge while playing the run well illustrates that Lewis could be a good 3-4 outside linebacker in the NFL. He could fit as an inside linebacker in the 3-4 as well.
Though he is a terrific athlete with an excellent first step, Lewis has never really developed as a pass-rusher. He isn't smooth off the edge, and he lacks a great rush move.
Lewis' athleticism and ferocious hitting ability make him an intriguing prospect, however. He can fly across the field, and no player wants to be hit by the Oklahoma DE.
As a rookie, Lewis probably won't contribute much. If he's playing linebacker, he will be adjusting to the transition and working on adding another pass-rush move. If he's at defensive end, he's a third-down specialist without great rush moves.
Ronnell Lewis will probably play DE for the Lions. Great pass rusher, lots of room to improve. Great pick and nice value.
