Lopez is the best current backcourter and possibly the best of all time. He is turning 26 in April I think so he could get even better-scary. Irastorza is a great backcourter, but I rank Lopez a tad higher. I do remember Atain and Felix as great ones. Elorza is another one I can think of. I don't see Urquiaga who played at Hartford mentioned much but he was real good-extremely reliable.
