Obviously this offseason is taking things to a different level. But we've had super-talented, AA-type guys leave before (just off the top of my head, Padgett, Giles, Downs, Bragg, Grimes, Thompson). I think this offseason is different in volume, but not in kind.
As I've said many times - I'm not wild about it, and I'm hopeful that this is as weird as it'll get before it finds a level (just like OAD chasing did). But I do think these sorts of things tend to fade away when we're winning games and headed toward another 1 (another 1-1, even).
