We have four point guards right now, that is evidence that a trade is coming.
Calling Barbosa a point guard is a bit of a stretch. Even when he's out there with a certified 2 guard (say a back court of Barbs/Hill/Jrich) he's really just a short 2 playing a bit of point because that's the only spot he could hope to guard. His game isn't really even a combo guards game. He's just a scorer.
