Of all the guys mentioned, Roberts is the only one who is in any way a traditional big in terms of style of play and of course he is pretty thin but I like his athleticism and nose for the ball. Steere will be the most complete I'm thinking but he's more of a 3/4 than a pure big but I don't see him getting out-muscled regardless of the competition. Keita wants to be a guard but unfortunately not a good rebounding guard! If he rebounded that would bring a LOT to this team. Otherwise it is like fools gold. I like having him on the floor for his size and he plays good defense sporadically but I don't like seeing him defending at the top of the key but I guess that is a philosophy thing.
