I would just flat out assume every area you are in will have cameras and/or audio bugs. Including the bus and the hotel. NFL rules don't say anything about the hotel so in BB world that means it's cool.
Leave fake plays books and call sheets around. Bring in some top level counter surveillance to sweep the meeting areas, coach's boxes, etc.
or you do what Secret Service does when the President travels, they do all those sweeps, then they erect tents inside the rooms they are assigned to and all the gear goes inside the tents. How awesome would that be to see? Big hotel conference room with a wedding sized event tent inside.
