With Oden injured, Portland only has Pryzbilla as a C. See ESPN depth chart. Raef is Joel's backup.

"With Greg Oden out for the season, Raef LaFrentz looks in store for a much bigger role at center for the Blazers."

In actuality Raef AND Channing Frye (another guy on my team) are supposed to see time at C with Raef getting most of the backup minutes. He's on the same team as last year playing the same role as in the past with the same coach in the same system.
