On the day the Colorado High School Athletics Association approved plans to begin a basketball season later this month, 820 miles away — in Phoenix, Ariz. — a handful of high school players from Colorado were quarantining in their hotel rooms in preparation for their 28th game this season. The 17 members of Colorado Prep were participating in their second iteration of The Grind Session’s “bubble,” where they played seven games in nine days against top prep competition from across the country.
