when he was a celtics he impressed me with his smart play and passing. but his shooting was abysmal (28% on 3 pointers) and he is physically slow on defense. just not athletic.
heck, if he can now shoot better, why not give him try. i doubt anyone from the g league will move the needle for the celtics.
p.s. i watched the video of him. he is WAY more muscular now than before.
