Since the MAC plays a lot of their nationally televised games during the week nights, they get more viewers just because the casual fan wants to watch college football on a Tues or Wed night. I think the MAC is the only show during those nights on ESPN/2. However, if any of those teams were to join a P5 conference and play their games on Saturday, their ratings would plummet.
I'm curious how many people have watched our Thursday night games.
