I'm also prior military. I'm not suggesting that the players shouldn't isolate even from their families. I'm merely suggesting that in the case of those with families, it's harder to isolate. In Kroft's case, we don't know his particular set of circumstances. Does his wife need assistance, for example, with the baby? I don't think the team is requiring it, and each player and coach has to weigh for himself what they are willing to sacrifice in pursuit of a championship.
