It's going to be really hard to split the hairs between Smart, Oladipo, McLemore, and Muhammad.
Agreed... though I'd throw Otto Porter in there with that group, too. I'd be absolutely thrilled if the Blazers were able to add any of those five players. In terms of their potential impact in the NBA, I'd currently rank them as follows (based on what I've seen from each guy at their respective schools):
1. Otto Porter -- good-to-great in pretty much every facet of the game; offensively & defensively. An extremely well-rounded player with huge, huge potential, in my opinion.
2. Victor Oladipo -- not quite as big or well-rounded as Porter, but possesses an absolutely dominant skill-level at the defensive end. Combined with his offensive efficiency & ability to handle the ball a bit, I really like him as a prospect.
3. Marcus Smart -- like Oladipo, Smart also possesses a dominant defensive skill-set, but I'm not quite as sold on him at the offensive end, yet. Reminds a bit of a PG version of Ron Artest, at SJU, without the crazy.
4. Shabazz Muhammad - Great offensive skill-set, which looks like it'll transfer over to the NBA pretty seamlessly, but there are a few red flags with Shabazz, in my opinion, as it pertains to the defensive end of the floor, as well as some intangibles. He could definitely end up as the best of this bunch, if he continues to improve upon his weaknesses.
5. Ben McLemore - I love his ability to score off-the-ball, but he doesn't quite have the ball handling ability to create much for himself or for others. I love watching him come off of screens and fill it up from the perimeter, I just think he has quite a bit to add to his game in order to make a big impact in the NBA.
