The biggest disappointment with Scal has been his inability to rebound. His defense is pretty effective on quick 4s and some power 3s (played Rashard Lewis as well as anyone on the Cs), his spot shooting is pretty effective, his screens are good, but he just can't rebound at all. Most guards are better rebounding the ball. This dramatically reduces his effectiveness as a big man.
I wish I knew how Scal was able to grab boards in his contract year with Jersey. He hasn't even sniffed those #s since.
