Garnett is still a good player, but there's no argument that his prime was wasted in Minnesota.
Reggie can't play a full season, nor does he need to. He was always one of my favorite players, but just like MJ, these age 40+ 'comebacks' are just ridiculous.
Can he still shoot? I'm sure he can. But if Boston finds itself in a spot next post-season when they need a 3 to force OT, then Garnett better be kicking it out to Allen or Pierce for the shot.
