I would bet that UConn could have had 1 coach and 7 scholarship players for Xavier not testing positive but chose to contrive ways to not play at Xavier shorthanded, based on contact with the positive players or others infected, and an 'abundance of caution', (ie code for we don't want to play a top 25 team shorthanded). We probably will never know if I would win my bet.
Hurley is also on record last year that he won't put a team on the floor that hasn't practiced, for the 'safety of the players'. (ie code for making sure they are prepared to win). It will likely be that UConn will not have the practice time before Butler, I suspect Hurley will press not to play, Irregardless of the 1 coach 7 player availability advertised BE standard.
I personally think if you meet the stated standard and don't play, you should forfeit, else scrap the standard. If a team does play according to that standard they are disadvantaged if others are avoiding games they could play.
