Matt Barnes is a member of the Memphis Grizzlies now, after the Clippers included him in the trade with the Hornets that brought Lance Stephenson to Los Angeles.

"He's just dirty" - Matt Barnes on Serge Ibaka. "... He hit Blake in the [groin] twice."

Ibaka did indeed; you can see the offending plays here and here.

We won't get into whether or not Barnes should be calling anyone else dirty, which is certainly reasonable to debate.

But given the fact that Ibaka and Barnes seem to want to fight each other, those regular season games between the Thunder and the Grizzlies can't get here soon enough.
