Players at this point don't know whether they're playing tomorrow or sometime next week. Some have been stranded in another city unexpectedly for several days. They'll soon be expected to play double headers, be subject to more schedule changes, possibly an uneven number of games between teams, and other structural or scheduling changes that are being made up as they go. Even with all the chaos of the new protocols and everything, all of this has got to have made it messier than most expected. In addition, Cain's quite possibly trying to figure out when/where/how his boys will go to school and didn't need all of these additional variables being introduced to that situation on a daily basis. Good on him for prioritizing correctly.
