If it causes a delay in title defenses I have a problem with it. If it doesn't happen before August 2013, they should both vacate their belts to make it happen. If they do that, I have no problem with it, particularly since Georges has said he'd want to stay at MW if he gains weight, and since Anderson would either retire with a loss or start looking at Jones with a win.
Do we need another super fight? No. It's honestly now or never though. Once one of them loses, the stock of this fight goes down tremendously. Weidman and Hendricks will be there. Just do this stupid fight now or be done with it. If it doesn't happen next, I don't want to hear about it anymore.
