There are reasons not to go to UK, but the only thing stranger than the reaction to Cal's recruiting results is the notion that he is somehow wronging these kids, or "brainwashing them." How? The guy has put a billion guys in the NBA (and not just bench types, bonafide superstars), so if you're goal is to get to the NBA, it's been proven you're better off going to Kentucky or Duke than UCLA or Indiana or Baylor.
Actually, stranger than that is the idea that the abolishment of the one-and-done would disintegrate Cal's system. I would argue quite the opposite - I mean Jesus, he had one of his best teams ever last season and only started one freshman. The guy can skin a cat in multiple ways and will continue to do so (see Tyler Ulis).
