Your guards are awful. First of all, you don't even have a two guard with any experience. You just play a bunch of bad point guards together. Your one good guard is leaving. Will Bynum literally cannot shoot, and Knight/Stuckey think they can much like Smith, but are bad chuckers that shoot 40%. Ditto Singler. This is bad. Bynum is pretty good at getting inside, but when you have Drummond/Smith/Monroe down there that will be taken away. No one on this team can shoot at all, seriously.
