That's what I'm saying. We have plenty of depth up front between Durham, Enoch, Diarra, Larrier, Jackson, Carlton, maybe Polley, etc. That's a lot of players for not a lot of minutes. Cobb doesn't address any urgent need, besides maybe rebounding, and he certainly is not a talent upgrade over those other players.
Depth does not necessarily mean good, however, and in adding Cobb, we are either no deeper or no better. Samuel would play sparingly, but you need players on the roster who are like that. Cobb is just adding another unknown to a pile of them.
