Of course the game fans will want to keep their tickets until/unless this thing gets too much.  The immediate problem is not the ticket holders.  It is the television contracts that truly support the league.  It was not the game attendance that brought the NFL to its knees in the early 60s. it was when the AFL got the ABC television contract. Two ominous facts are that viewership was down 14% before this recent escalation and that so many of the television fans are in agreement with President Trump.
