If there's an amnesty clause in the new CBA, I'm certain Horcoff will be bought out (they like the player, but it's clear to everyone including management that his contract is out of whack and could potentially cause problems down the line). If that happens, I think they'd just give him #10.
If Horcoff is still here next year, then I could see him wearing #96 for the same reason he wears 10 now. Bure's number.
I could also see him wearing #12 for his draft year as well.
If you are offended by this post, it's probably because you're ugly.
