I made a post on him in the Chad Ford thread a few days ago.
Very intriguing player and one of my favorite candidates for one of our first round picks.
Has a Corey Brewer physical/athletic profile, but a much more appealing offensive game. Has very good touch 15 feet and in and a diverse assortment of shots - floaters, pull-ups, scoops, push shots. Nice footwork too - I can see him doing a lot of damage in a Rip Hamilton type role. Solid passer too.
The times I saw him play, Memphis was playing a full-court press against some overwhelmed college guards, so I'm not sure how much can be taken away for NBA purposes, but Barton's length and athleticism are certainly effective in traps. A lot of deflections. He's a blur in transition too.
