They are saying that it is starting to look like we will see all conferences delay the season and be playing in-conference only and without a postseason. Because there are situations where teams won't be allowed by state or school restrictions.
The Big 10 has already made the announcement. The Pac and Big 12 are expected to join them as early as tomorrow.
A handful of teams are expected to pull out as well. I've heard Stanford, Wisconsin, Northwestern, Rutgers, Wake Forest and USC all mentioned as teams that might cancel on their own.
Notre Dame is supposedly in talks to take a teams spot in conference play in either the Big 10 or ACC.
