The Warriors’ decision to waive veteran forward Omri Casspi for Quinn Cook paid on-court dividends at the close of the 2017-18 NBA season. Casspi had picked up intermittent DNP’s throughout the year, was sidelined with an ankle injury, and the team needed a point guard to step in for then-injured All-Star Stephen Curry.

But while the move appeared to be based primarily on need, Casspi and the Warriors were not always on the same page behind the scenes, Ethan Strauss of The Athletic writes in a Q&A.

I don’t know if was a ‘blowup’ necessarily. There was a lot of frustration on both sides, though. Generally speaking, he didn’t perform like the Warriors expected and they felt his attitude was suboptimal.

Casspi signed with Golden State in July of 2017 with both parties under the impression that he would play a significant role off the Warriors bench.

Instead, Casspi saw his minutes dwindle as the season progressed, ultimately averaging just 14.0 per game—fewer than some of the teams greenest players, including second-year guard Patrick McCaw and rookie second-round pick Jordan Bell.

Still, Warriors coach Steve Kerr was distressed by delivering the news that the team was going in a different direction, per Mark Medina of The Mercury News.

“It was difficult to go ahead and go through with it because he has been with us for all season long,” Kerr said. “We love Omri and what he brought to the team — a great teammate. It was difficult to sit with him and tell him we were going to do this.”

Casspi had previously expressed interest in re-signing with Golden State. He agreed to a one-year contract with the Grizzlies in July.
