At least 19 teams have confirmed that they took extra precautions when playing the New England Patriots due to concerns about spying.

Steps teams have taken against the Patriots include running fake plays during walk-through practices in case the Patriots were spying, not leaving anything sensitive in the trash at their hotels in New England, declining the Patriots’ offer to use their facilities, blocking off the visitors’ locker room at Gillette Stadium to keep Patriots employees out, sweeping for bugs, and telling the Patriots’ visiting locker room manager to leave because they didn’t trust him not to spy. 

Reports suggest Roger Goodell was determined to punish the Patriots for Deflategate due to the perception he went easy on the franchise for Spygate.
