No idea why. I follow Jimmer and look at the Kings "box score" after each game to see how many minutes he played and how many points. I think he's been pretty effective considering the limited minutes, and coming off the bench. I cannot imagine that it's a discipline situation.
On a side note, I read yesterday that the Kings have been sold to a group that wants to move the Kings to Seattle and will become the Sonics. The deal is done, just waiting for NBA approval. To make the move, the paperwork must be filed by March 1st.
