At least in the pre-season, an argument could be made that getting the players on a campus and giving them a strict testing and tracing regime (and quarantining those that test positive) may be safer than leaving those athletes to train and mingle on their own.
That said, once school starts and all of the students arrive on campus, will be much harder to test, trace and isolate positive cases. Are schools going to test every student upon arrival and keep testing them during the semester? I know that will be the plan for the athletes, but to be effective, all students/profs/staff should be tested as, even if the plan is to try to maintain "a bubble" on campus, that plan only works if everyone is tested and traced, not just the 85 football players and 13 basketball players.
They probably should regularly test everyone (and have isolation facilities in place) if they want to open campuses in August to all students, but wonder if schools are willing/able to incur the cost and have the infrastructure set up to do that.
