My rationale for why the season won't happen is pretty simple. Jamie says that the student athletes will be safer and more isolated at ISU. But even in a normal season, they can't stop players from going out and getting in trouble.
If universities want to play the games, and bring in revenue for the school, the athletes have to be completely isolated from the outside world, similar to what we see the pro leagues doing. But then what about the other part of the magic term that makes college sports what they are: STUDENT-athlete. Are the players allowed to attend classes? What happens if a classmate or a professor tests positive? Most of these players live in university housing, how do they avoid other students?
And one more angle that isn't coming up with these discussions: what about the coaching staffs for these teams? ISU has a relatively young staff, but what about someone like Saban, Lovie, or Mack Brown? They are at much higher risk for the adverse effects that come with this virus. Can they be reasonably isolated?
I think all in all, is it will be too hard to maintain isolation while still carrying out a season that involves 150+ players and staff per team.
