I still don't think they should give up on Harry Giles. He is much leaner than Nurk, but he essentially has the same standing reach and wing span. He is more athletic and can shoot better from the 3 pt line. Not saying he is more effective than Nurk because he is not, but on paper, he seems to be a solid backup center when the goal is to defend the perimeter.
I hope this does not turn into another Moses Brown scenario where we think he sucks because he never got a chance. Granted he did not look great when he did play, but he definitely showed flashes of being skilled at most things. (Decent passer, ball-handler, runs the floor, blocks shots, hits some 3's, decent FT shooter.) He is not the offensive rebounder as a Kanter, but few are.
