UPDATE: A tidbit from Tyler Forness of Climbing the Pocket sheds a little more light on this move.
Great nugget in here from @MichaelDavSmith
“The NFL is requiring Tier 1 staff — the people in closest contact with players, such as coaches and equipment managers — to get vaccinated. Players cannot be forced to get vaccinated.” https://t.co/pghOMHA8Hb— Tyler Forness (@TheRealForno) July 23, 2021While the league can’t force players to get vaccinated, they have apparently mandated it for coaches and other staff that have close contact with the players.
