Beaubois has very weak PG skills. Not a floor general / organizer of an offense. Nor is Beaubois a playmaker who can create for others. He is not really a solution to this lack of a PG issue.
Beaubois is just another combo guard and an inferior one at that to the guys already here (Bradley, Lee, Barbosa, Terry).
That said, I think Beaubois would be a good fifth guard in the depth chart though. I would be happy to have him in that role if acquired at a low cost (2nd round pick?). Provide some useful depth.
