Here is my solution. Push all playoffs back one week, take 64 teams as usual. If there are not enough teams to fill the brackets then give byes to the higher speeds. If it is not possible to move the playoffs back due to logistics, such as availably of championship venues. Then reduce the number of teams to 32. For teams that cannot resume the season, then all their seniors would be granted an extra year of eligibility (but they must stay at that school). Finally, if any seniors want to transfer to another school, then they be granted immediate eligibility.
