They have 3. Durant, Westbrook, and Martin.
Martin isn't a great playmaker anymore, but he still gets himself to the FT line a decent amount and is a good bench playmaker. He just gets compared to Harden, which isn't fair. Their problem is lack of versatile big men, lack of versatile role players, and lack of an offensive system outside of ISO (which probably contributes to a reason their role players don't look that great).
He said "roughly" one..
