You are right on regarding revenue. A sold out home game brings in approximately $1.2 million in ticket revenue, plus concessions, so a home game is much more financially valuable compared to a trip to Provo or almost anywhere else for that matter.
Where I'll correct you is in regards to the Pac12 Network. Every conference game will be picked up by Fox/FX, ESPN/ABC or the national Pac12 Network. However because of overlap during out of conference games there are going to be 3 or 4 games that will only appear on the regional networks. None of those games involve Utah.
