Per Howe in the Athletic — it wasn’t even meetings. It was “office hours” where players could drop in.
The rules infraction had nothing to do with on-field activity. Rather, the Patriots posted a schedule of voluntary special teams office hours to let players know when coaches would be available if the players were interested in dropping by for a meeting, according to a source. An NFLPA representative noticed the posted schedule during a routine visit to the facility and informed the team the schedule could give off the impression that the office hours could be mandatory.
