Billy Donovan keeps losing his assistant coaches, and there's a good reason why

First, Bob Beyer left for the Sacramento Kings. Then Mark Bryant and Darko Rajakovic left for the Phoenix Suns.

And suddenly Billy Donovan had lost 60 percent of his coaching staff.

The Thunder largely is a secret society, so it’s hard to know what goes on behind the closed doors off Britton Road. But in this case, it seems sure that things are as they appear. The job security that has been a hallmark of this Thunder decade is not necessarily going to last.

Donovan’s contract is up after next season, and two straight playoff disappointments has created no appetite for an extension, inside or outside Thunder headquarters. The staff could be looking for lifeboats already.
