ACC colleague Notre Dame on Friday attributed an infection spike to an off-campus party where masking and social-distancing guidelines were ignored by some. In the Big 12, every resident of an Oklahoma State sorority house is quarantined after 23 people tested positive.

The NBA and NHL have shown that a bubble can work. College is not a bubble, though UNC may be trying to create one.

Four FBS leagues — the Mid-American, Mountain West, Big Ten and Pac-12 — have shuttered fall sports, and the Pac-12 explained its reasoning with a coherent, 12-page report from its medical advisers.

This was in stark contrast to the Big Ten, where ineffective messaging has fueled open revolt and scarred the conference.

The ACC, Big 12, SEC, American Athletic, Sun Belt and Conference USA owe their athletes, coaches, staff members and fans clarity, regardless of their decisions. Often rivals, but partners in this quest, the ACC and SEC are on the transparency course.

Last week, the chairman of the ACC’s medical advisory group spoke to the Sports Business Daily, and a member of the SEC’s panel answered questions from The Athletic. Previously, the team doctors from Virginia and Virginia Tech, John MacKnight and Mark Rogers, outlined the challenges of staging sports during a pandemic.
