The part of Dana's quote I bolded makes me believe he's not referring to the win bonus but probably to a "locker room" bonus we aren't privy to know about. We all know about the various public bonuses.. KOTN, FOTN and the win bonuses but it's long been rumored that the UFC pays out substantial locker room bonuses that we don't know about for various reasons.
My guess is that is the bonus Dana is talking about and it was probably a lot more than 15K imo.
