I feel bad for the guy. After having a fairly mediocre/poor year in Philly and then a bad season with Dallas--not a good fit--he's played well
for Boston and I'm sure was pretty happy with his role and having Grant Williams as a teammate. He was a good fit in Boston, and he seemed to regain his confident shooting the ball, which had been his problem the previous two years (did not shoot well). The hard-core Celtic fans
mostly wanted to keep him, even has he's become one of these complementary-type role players now who always seem to be trade bait. It can't be easy getting moved all the time. A lot of guys are traded frequently in the NBA, and most of the trades seem to accomplish very little. Wish him well.
