Any player that has 'combo guard' written into his description. A: Jack of all trades master of none. B: We have a combo guard in the 'core four' named Burks. Oh, and Hayward kind of too. Don't need another.
(Yes I know I just contradicted my self basically saying that Hayward and Burks master nothing, but I would like it if they could stick to being 2's and 3's and leave the point guard to a real point guard. Oh, and Mo's a combo guard.)
