I know this question has been asked before because I even remember reading it lol, but can suspended players/coaches contact each other while they are in "timeout?"
But the answer is no. They cannot have any contact with anyone associated with the NFL without consent from the league offices. They are just suspended, not fired, so they are still associated with the NFL. Hence, no contact with each other whatsoever.
IIRC, Vilma has consent to talk to the Saints trainers about his rehab process. But that is the only approved contact.
