Why? You can't just drop this turd without an explanation. Whether if CW is 6'6 or 6'4 his wingspan is bigger than Gessell or Clemmons. That alone makes him just as strong a on-the-ball defender as Clemmons or Gessell. So what are we talking about? Lateral quickness? Experience?
Gesell and Clemmons were really good on the ball defenders. Just because CW is longer doesn't mean he will be as good as they were
