Disagree. The depth of a rotation is overrated. With an 8-man rotation, you can give everyone enough rest.
C Blair - 26
PF Duncan - 32
SF Jefferson - 33
SG Hill - 32
PG Parker - 32
C/PF McDyess - 28
SF/SG Ginobili - 28
SF/SG Mason - 28
That rotation would allow for everyone to stay reasonably fresh. An 8-man rotation, as long as each of the eight players is getting 25+ minutes, isn't too taxing.
The rest of the players would get playing time due to either foul trouble or if something is needed such as shooting (Bonner or Finley) or defense (Bogans).
When Pop gets serious with his rotation, it has usually been a 9-man rotation. The only difference with this arrangement is that Hill is playing roles that usually necessitate two players: starting shooting guard and backup point guard.
