Giants owner John Mara has written an essay warning that the players’ strategy in the labor impasse, if successful, would lead to chaos in the NFL. Mara’s comments, posted on the team’s and league’s websites, point to the possibility of no league-wide minimum player salaries, “with many players making less than they do today,” and no minimum requirements for spending on team salaries, “with many clubs cutting payrolls the way some teams do in other sports.”
