McCallum making Thomas expendable?

If Ray McCallum's past week is any indication of what's to come for the rookie second-rounder out of Detroit, we have to wonder if it could impact Sacramento's negotiations with Isaiah Thomas when he becomes a restricted free agent this summer.

The Kings will have the right to match any offer sheet for Thomas, one of the league's top overachievers since being selected with the final pick of the 2011 NBA draft, but with McCallum filling in nicely for Thomas as of late we might have to wonder if the team could see him -- not Thomas -- as the team's point guard of the future.
