GM Martin Mayhew loves to take the best player available, and Lewis was certainly one of the top players left on the big board at pick No. 125.
Lewis is 6'2" and 253 pounds, and fits nicely into the 4-3 scheme of the Detroit defense. He has good lateral quickness and excels at pass-rushing. Lewis' athleticism is a strength for him, and he will track down ball-carriers in the open field.
He was actually nicknamed "The Hammer" by his teammates at Oklahoma because of the ferocious nature of his hits. This is a guy that will get after the quarterback and go hard on every play.
If there is a knock on the former Sooner, it is that he struggles with play recognition at times. But that can be worked on and his motor will allow him to make up for small mistakes in his reads.
Detroit may already have a great starting trio at linebacker in DeAndre Levy, Stephen Tulloch and Justin Durant, but behind them the cupboard is rather bare.
Lewis is a perfect addition to the depth chart at a position of need.
He was a projected second- or third-round selection and has great value in the fourth round.
The Lions are tackling their needs one by one, and aside from Ryan Broyles in the second round, they are avoiding reaching for talent.
Now, having taken an offensive tackle, wide receiver, cornerback and outside linebacker, there are few glaring holes that remain. Perhaps some more defensive back help and a backup quarterback will be added.
Overall Grade For The Pick: A
Again, Detroit addressed a need at linebacker while not reaching for a player to fill that need. Ronnell Lewis is an underrated prospect with a ton of potential and could blossom in the Lions system.
He will not start right away because of the starting talent the Lions already have in place, but he is a good piece behind them and can contribute on special teams right away.
(I had Detroit taking Lewis in my Day 3 mock from this morning. Check the rest of that mock out here.)
