One name keeps popping up as the solution to so many of the Celtics problems. And it's the same name that we were searching for fourteen years ago. Kevin Garnett.
KG turns 45 in a month so you're not bringing him back to play. And he has no head coaching experience, nor has he ever expressed an interest in being one, so scratch that option as well. While KG has worked with players, I don't see him coming back to be an assistant coach. No to bring KG back Wyc Grousbeck should make Garnett the offer he can't refuse.
