I'd go with Snow, though Varejao would be a fairly close second. Pretty pathetic when a thirty-something, slowing down guard is the best defender on the team, and the second best is a youngster with very little professional experience. I agree that Newble's defense is over-rated, but he, Harris, Welsch and Traylor are at least adequate defenders. Reminds me that beefing up the defense is probably the single most important goal that next year's general manager and coach should focus on.
