Chris Kaman returns to starting lineup

MEMPHIS -- No wonder Chris Kaman has "zero idea" what his role is.

One night after being a DNP-CD, Kaman is in the starting lineup. It's his first start since Jan. 20.

Kaman was demoted for two games before suffering a concussion that sidelined him for 10 games. He played eight quality minutes in his return Sunday against the Los Angeles Lakers but never got off the bench for Tuesday's loss to the Milwaukee Bucks.

Bernard James, who had been starting at center, is healthy and available to come off the bench.

The starting lineup of Kaman, Dirk Nowitzki, Shawn Marion, O.J. Mayo and Darren Collison is 5-4.
