@cplach Hargrave can play both DE and NT, and we also picked up Mathews from the Chargers. Both are vast improvements over Cam Thomas and Cliff Geathers. As for RB I agree that we're going to need some depth there, maybe rounds 3-5.
Moves well off the ball, especially coming off screens
Effectively utilizes runner in the lane
Decision-maker; doesn't force much
Needs to get stronger
Attacking the basket
Finishing strong in the paint
Taking defenders off the bounce in iso situations
Lacks ideal NBA athleticism
Summary: Lamb was one of the better pure shooters in college basketball this past season. That is where he can make his biggest impact at the next level; being a shooter off the bench. I am not sure his role will be anything more than that though, which is why he projects as a late first-round pick.
Player Comparison: Leandro Barbosa. Despite being undersized, Barbosa has had a successful NBA career coming off the bench as a scorer. Lamb will likely fill a similar role on whichever team he ends up on, and like Barbosa, he has a great touch as a shooter.
