Exploring the history of CelticsBlog, in 2006-7, Doc Rivers was a terrible coach (rotations, rotations, rotations). Then, in 2007-8 he was a terrific coach (meshing the Big 3 and melding together the old and the young). In early 2008-9, he was still a great coach (developing Rondo, BBD, TA and managing the personalities). However, in late 2008-9, he was an awful coach again. Then, in early 2009-10 at 25-3, he was a wonderfully skilled coach. Now, in a 13-15 run , he is inept.
Baloney to all. Rivers, as a coach, does some things exceptionally well and other things average. When his players have been healthy he has done as well with this team as any coach in the NBA would or could (including an historical start in 2008-9). When his players are unhealthy and/or tired/slowing down he is balancing a completely different dynamic and therefore his rotations change (and he and the team struggle). He does make mistakes, but overall he has been as good for this team as any coach (with a few exceptions) could have been.
