Home schedules as an independent:
The lean years - there were few P5 home games or regional games that would be high attendance games (Boise State, Utah State). 2012 and 2013 were good but the others only had 1 or 2 "good" games on it.
2011 Utah, UCF, Utah State, San Jose State, Idaho State, Idaho, New Mexico State
2012 Washington State, Weber State, Hawaii, Utah State, Oregon State, Idaho
2013 Texas, Utah, Middle Tennessee, Georgia Tech, Boise State, Idaho State
2014 Houston, Virginia, Utah State, Nevada, UNLV, Savannah State
2015 Boise State, UConn, East Carolina, Cincinnati, Wagner, Fresno State
But starting next season, the independent home schedule really seems to turn around with 3-4 of the 6 home games what I would classify as "draw" games (P5 or good regional games with tickets in demand) and I would expect to see attendance jump accordingly.
2016 UCLA, Toledo, Mississippi State, UMass, Utah State, Boston College [tentative]
2017 Utah, Wisconsin, Boise State, San Jose State, UMass, TBA
2018 Cal, Utah State, Northern Illinois, Hawaii, TBA, TBA
2019 Utah, USC, Washington, Boise State, TBA, TBA
2020 Michigan State, Utah State, Missouri, TBA, TBA, TBA
2021 Arizona State, Boise State, TBA, TBA, TBA, TBA
So if someone dropped their season tickets due to weak home schedules in recent years, I'd go pick them back up.
