A college football fan can invest his/her entire day (driving there, tailgating, watching the game, driving home), or spend the day watching every game, including the Zips, on a 65" HDTV.
A Zips fan can only take so much losing in their lifetime. I would be embarrassed to add up the amount of Zip losses I have witnessed in person, and I'm probably not even in the top 1k. Most Zips fans are Browns fans as well, how many times can that fan watch their team lose on Sat, only to turn around and watch it happen on Sun as well. The Zips\Browns fan is a special kind of person. There should be a local therapy office specializing.
Many more reasons, but they are all excuses. Winning solves everything. I'm confident JoMo has the Zips on the right path. Once they become an entertaining team, fans will show up.
