We all continue to be optimistic when it comes to the upcoming college football season but that doesn’t mean there won’t be challenges that programs across the country have to overcome in order to have the season play out.

According to Dr. Anthony Fauci, one of the nation’s leading infectious disease experts, the key to holding the season may center around keeping the players isolated from the rest of the world during the season.

“Unless players are essentially in a bubble — insulated from the community and they are tested nearly every day — it would be very hard to see how football is able to be played this fall,” Fauci said in an interview with CNN.com. “If there is a second wave, which is certainly a possibility and which would be complicated by the predictable flu season, football may not happen this year.”

It’s unclear how realistic it is to ask college football players to isolate themselves from others this fall but that may be necessary for the season to be played.
