The incremental difference between football practice like BYU and conditioning that the U is currently doing is too small to measure. The Pac 12 and Big 10 could chose to get ready for a late fall season like the others and openly talk about the criteria that must be present to continue. A team or a few that need to cancel a week is small compared to giving up on the year. I have zero idea as to why spring football had an advantage over fall football at this point. They will always be forgiven for trying and failing more so than punting the season.
What should be a question is just how many fans under what circumstances attend the games. I think all will accept any process for attendance to have the games on TV. Focus on incremental risk and reward the programs that manage risk best.
