Are you guys serious? I live in Utah and watch Football EVERY SUNDAY. Not only that but I usually have 4 or 5 friends over too. So if even 25 percent of people in Utah watch football like me (extremely low estimate) that's about 700,000 people. Then you can't forget about the 4-5 friends they will bring with them. That's a fanbase of roughly 3,000,000. Now if we're realistic and say that only 10% of those people are going to come I every game that leaves 300,000 people. Quickly the problem becomes building a big enough stadium to house everyone.
Also, some of you are forgetting the marketability of "Monday Night Football Family nights." We could just schedule half our games every year for MNF. If its a choice between family home evening board games or going to the stadium for MNF family nights what do you think most people will prefer? Geeee hmmmm let me think about that.
You can't schedule half your games for MNF. The NFL schedule those games and won't let a Utah team have that many.
