How the fuck can the ref be on 10% of the overall fight purse? Someone must be pulling your leg?

Why would Team Floyd/Manny give $10million to a guy to do a job millions would do for free? If I was a top Vegas ref i'd start subtlly bumping the others off.

I've read about managers/team members (Frank Maloney with Lennox Lewis) being reduced to 1% of their fighters purse in these mega fights. I would expect the ref to be on less than that.
