Roy Exum: Career Vs. Vaccine? Sunday, July 25, 2021 - by Roy Exum Roy Exum Rick Dennison is easily one of the top assistant coaches in the National Football League. He has spent 27 years in the NFL and had his teams go to 13 playoffs, win five division titles, and has earned three Super Bowl rings. Yet on Saturday there were strong story lines he has been fired from the Minnesota Vikings because he refuses to take the COVID-19 vaccine. While our Constitution gives every American the right to refuse the vaccine, it doesn’t forbid businesses, schools, and organizations from requiring it. And that’s as fair as it can be. When you work for a man you play by his rules, not yours, and if you “adamantly disagree,” you have the freedom (and the hasty opportunity) to work elsewhere.
