WCS is still not a good rebouder in all liklihood. He's just not a 1 rebound a game guy. Tall, skinny, mobile, runs around on the perimeter a lot chasing and showing. In some ways what he does is not built for defensive rebounding, which is a big problem if he's your only big because if your 7-footer won't do it, who will? Its not a big problem if he's in there next to Cuz or Koufos. Maybe he rebounds like a Dirk, or a Gasol or Brandon Wright or whatever, non-rebounders who just get enough. they will have 1 some nights, 8 or 9 others. Only a smattering of double figure games. But with Boogie munching them up that's ok for us as long as there is a reason for the board weeniness, and that reason is he's in defensive pursuit-mode.
Hew may never play full starting minutes, but if he was just a 7-8 guy in full minutes, that's enough next to Cuz. A 5-6 or less guy is not. Now you're talking full on wuss letting other teams walk over you to get to the glass.
P.S. while I don't think Webber did him justice, the one thing about Webber's rant that was correct is that WCS is never ever going to have a DeAndre like impact, because there's an enormous gulf between them on the glass. WCS is a true specialist of a different sort, not a big numbers guy. you're going to have to track his success via impact numbers, not bulk stats.
