One of the mistakes I believe the NFL made this year knowing covid was happening , was not letting rosters expand. I know they put new practice squad rules in place, but they should've allowed teams to have something like 20 reserve players for covid, this would be on top of the practice squad. Pay them league minimum or less, put them in some kind of bubble so they're on call and ready to go at any point in case of an outbreak on any given team. I know that's much easier said than done, but it really wouldn't have been all that hard. There's 90 players on every team going into training camp. I'm sure the NFL could've figured it out in the off season
