Funny, in 2005-2008 everyone thought Doc was a great offensive coach and clueless defensively. They credited everyone but Doc for the 2007-08 defensive turnaround.
Now the Celtics can hold the best offensive teams to less than their average and close to 90 PPG and the offense sucks and now Doc doesn't know how to coach a team offensively or get rotations right.
OR................
Maybe Doc is just a [dang] good coach but is severely limited by the players and the health of the players he is given.
