Smith is an interesting case on several fronts. He was an outstanding freshman at Iowa, transferred to Tennessee and was granted immediate eligibility due to medical issues with his father. Tennessee was already pretty darn good, but Smith became a focal point in their offense, which to Tennessee fans was somewhat odd considering Chris Lofton was still around.
Now that we know Lofton was battling cancer and strength issues all season, the emergence of Smith as a go-to guy on offense makes sense. Smith made the biggest difference on the defensive end. He made key blocks every game, could rebound, and his toughness was unparalleled. He has the look of a guy you don't want to mess with, and his game should equate interestingly to a Joakim Noah-type player.
I don't think Smith will be a great NBA scorer, but I think he will go in the late lottery next season and become a solid NBA sixth man. For a more established comparison, I'm thinking in the mold of Quentin Richardson, minus the long-range distance. All three players are athletic and can rebound well. Richardson became a good shooter, something that will never happen for Smith, but Smith could become a hybrid of both players.
