Utah got $2.2mm for the championship game. Plus around $1mm from KJAZZ. So approximately $2mm more than staying in the MWC.
Utah may well end up with a top 25 recruiting class this year as well. Already have five 4* kids, and more very close. Currently ranked #28 and they aren't done yet.
Plus, the PAC12 Network was not factored into the numbers provided, nor was the $$$ from the BCS. All told, Utah should anticipate between $20mm and $30mm per year, starting in 2014, which is when they are full equity members of the PAC.
It would be interesting to know what BYU's actual numbers were this past season. I would imagine pretty nice actually but we may never know.
