well, even the 6 figure contract is a bit misleading. I dont have a source on hand, but I understand its a 100,000 contract for 6 fights. So roughly 17,000 per fight, higher than the likely 5-10,000 everyone else is getting from the show, but not a huge amount amount more.
Even the fame that comes with winning is a bit diluted now – with so many seasons. Ive watched every season and it would take me a few minutes to come up with every winner. I think big country is an exception, because of his unique appearance and character, but the last few season the winner has kind of fallen off the map within a year or so of the season ending.
The real reason for the show in my opinion is to sell the PPV. GSP vs Koscheck is the money maker and the show is essentially a 10 week prime time series.
