There is a gigantic world of difference between the NBA and college football. For one, the NBA actually pays there players, and two they can put the entire league in a bubble. It is impossible to put one CFB team into a bubble, let alone an entire conference worth of teams. Baseball has like one third of the players of a college team, and even the MLB can't prevent outbreaks.
If anyone plays football this year, kids will get sick, coaches will get sick, and there's a very good chance someone (probably a coach or staffer) dies from it. Not to mention some of the long term effects they've been seeing like lung and heart disease.
