Worth a notice, I think. It's good to see him get some burn in the Big Show.
I think that he's got an NBA future and was a great value pick at 53. Whether or not he's got a future in Boston is another story - I doubt it, since he's playing behind three big ballhandlers plus Pritchard. Since all four of them are now rotation players, there is not a lot of space for him to get any more than spot minutes, even with Mazzulla running a lot of two-ballhandler lineups.
Still, there's a lot to like.
He's got a great NBA body and excellent fine motor skills. Long torso, great extension, good laterals and footwork. Has a nice finishing burst and emerging change-of-pace dribbling moves. His stroke is beautiful, and he's got smooth movement through his spine as he launches, so there's hope for his shooting.
The difference in his left hand since the end of his college career is big - moreover, it's a good indicator that he's got a work ethic.
