Withey was second in the NCAA behind Davis in blocked shots the year before last. Just out of curiosity, I looked up
who held led that stat by year.
Over the last decade, it looks like you've got Anthony Davis, Okafor, and a bunch of no-names you've never heard of. Shot blocking in college doesn't seem to translate well to the NBA, at least not if that's basically your only skill. Most of these guys, just like Withey, were long skinny guys who probably just didn't have the brawn to hack it in the league. Most of them averaged more blocks in their record season than he ever did in college.
Like most second rounders, he's most likely going to wash out of the league. He did have a nice talent at the college level that we could definitely use, but it seems pretty unlikely that it'd translate to the NBA game.
