I disagree with Idaho's remote location being the reason why Idaho failed in the FBS. The primary reason why Idaho failed in the FBS is it had no home, no regional teams to compete against after the collapse of the WAC. Idaho was doomed to fail in 2013 when they had to go the independent route. The Sun Belt was not a sustainable option for the four years they were a member until the Sun Belt kicked the Vandals out. And since the team was not going to be a member of the PAC12 or the Mountain West, the only option was to move back down to the Big Sky.The biggest mark against Idaho was the remote location. Facilities too, but being in the middle of nowhere was a big problem. Especially when those fucking retreads networks started making decisions solely on the number of tv's in the school's footprint.
Facilities are definitely a piece of the puzzle, but the biggest problem 100% was Idaho's inability to have a western FBS conference to call home.
