I wouldnt mind it, but I do think Caldwell is better at C. It all depends on what we do in FA. If we get Brown in FA, all C's are off the table to me. Eric Wood at G/C? Maybe. Not likely if that happens.
I don't know if C would be completely off the table if we got Brown. Sure we would have Satele at backup C/G, but with the amount of good C's coming out and the fact that it can give depth at C and G (with Smiley and Thomas both coming off injury, its a little more of a concern), it wouldn't surprise me if we did pick up one in the later rounds.
Though I have to say, if we got Brown, I'd be a lot more concerned with getting a backup T rather than a G.
