The National Football League celebrated its 100th anniversary last year. This should be a time of self-congratulation for the brutal sport, which has no similar counterpart outside the United States.
The NFL’s megaprofits dwarf those of other professional sports in the United States. The Super Bowl, not the World Series, is America’s national sports event.
The league survived all sorts of crises in the past.
Yet the NFL is in deep trouble like never before.
