"This is just one of the many problems with modern roster construction. Already playing short-handed, teams are crippled when an illness or minor injury makes even one player unavailable for a day or two. There is absolutely no built-in flexibility to cover for the flu, for food poisoning, for a rolled ankle that will be fine in 48 hours, but which requires a day off to heal. In cases where teams are down two players to minor injuries, not the most uncommon happenstance over 183 days, they're effectively playing with no bench, no in-game tactical options."
