I disagree.
Yeah, Booker needs to be better at beating doubles, but our offense is too often far too stagnant. If they are throwing a double at Booker (or anyone) then the other guys should be moving and forcing the other defenders to react. Doubling is easy, especially in a half court trap, if the other 4 guys are statues and the defenders can basically play "free safety" out there, just waiting for a pass.
They've been somewhat better about it since Beal came back, but it mostly guys moving after a ball handler gets penetration, rather than players running the wings and cutting off the ball.
