Warriors' offseason 'painful', says Kerr

LAS VEGAS - Golden State coach Steve Kerr knows that a new era of Warriors basketball is about to begin.

He just doesn't know what that means yet.

It has been a rough summer for Kerr, whose roster is wildly different following the offseason departures of Kevin Durant, Andre Iguodala, DeMarcus Cousins and Shaun Livingston - all on the heels of the team losing the NBA Finals to Toronto and Klay Thompson tearing an ACL in the last game of this past season. He spoke of the summer of tumult on Monday, when USA Basketball opened its World Cup training camp.
