I'm not sure, I agree it would be a real shame for Holm to now go and lose straight away. If that happens, she kinda fucked Ronda's legacy for nothing. It's a question of: would I prefer Holm to continue winning and retire undefeated (although not nearly as impressive as if Rousey had done this), or have Rousey come back even stronger and finish her career with but one flaw. OR there is the possibility the will keep trading wins back and forth, that might be kinda cool if that happens.
I'm not sure right now; I'm on the fence. :)
