CFB in 1994: Saturday at noon or 3:30 pm against a team (minus a couple warm ups) you play every year or an intersectional name you rarely play and want to know how you measure up. There are maybe two or three other games on TV. You do this every Saturday, you plan for it, your friends plan for it. If you are a student, it is the primary social activity during a fall weekend. Sometimes you load up and travel to an away game because you can.
CFB in 2018: Thursday, Friday, Saturday, and sometimes Wednesday at all hours of the day, only you don't know which hour until 6 days prior. You play teams you play every other year for the last 10 years or less, you play familiar teams less often or not at all. There are at least a dozen games on TV and nearly every game is online. The gameday experience is disjointed is a less universal for fans of all schools. There is more happening on your social media account than on the field and you are more connected to other fans though apps than in the stands. Spending the time prepping and attending a full day/weekend event is less appealing with other options. Away games? You'll need a plane.
