Smith rips Jennings, backs brother

J.R. Smith appeared to threaten Detroit Pistons guard Brandon Jennings on Twitter in response to Jennings questioning whether Smith's brother, Chris Smith, belonged in the NBA.

On Wednesday, Jennings sent out the following tweet, which was later deleted: "Wait wait wait JR smith brother is in the NBA but @PoohJeter & @BBROWNLAU isn't. Call me hater but not Rollin!!!"

Shortly after the Knicks' win over the Atlanta Hawks on Wednesday night, J.R. Smith responded with a tweet appearing to threaten to send his "street homies" to Detroit, presumably to confront Jennings.
