The virus seems to have given the final push to a number of wealthy veterans, some of whom have had a lot of success and some of whom have lost whatever love of the game they once had, to see what retirement will feel like. Ultimately, this will be to everyone’s advantage.
Don’t think there’s any conspiracy. These players have all won, all earned more money than most people ever dream of, have legitimate reasons not to play the season and/or just decided they don’t want to risk getting ill to play a season for a team that is in decline because of the age of players and a step backwards or three in quarterback play. Who knows? A couple of them may have been iffy about playing a normal season.
