It would mean the Cowboys would have to find a site fee of many millions to beat what the MGM will be offering, even with all the extra ticket sales. If they sold 70 000 tickets more than the MGM at $100 a ticket that's only seven million more than the MGM gate would pay. MGM will make seven million in the casino from one or two of the hundred plus high rollers that the fight will attract, they can afford to offer an enormous site fee.
