Memphis Grizzlies wing Matt Barnes joined SportsNation on Tuesday, and didn’t hold back when asked about Oklahoma City Thunder big man Serge Ibaka, with whom Barnes feuded while with the Los Angeles Clippers.

“He [thinks] he’s the toughest guy on the planet, he’s not.”

Barnes said he’s really about that life while Ibaka just pretends.

Them’s, quite literally, fighting words! Ibaka noticed this, and fired back — although he didn’t seem to be overly concerned with Barnes’ semi-challenge to a fight.
