The football players were 'done'?
At the end of the movie, McGinty's voiceover talks about how, after that final game, the players had no endorsement deals, etc., implying that those four games were all they were ever going to get. To which I can only say, "Ha!"
Sure, some of the players might have been blackballed in the aftermath of the strike (Falco being most likely, if Martel had any real influence), but Gruff, Wilkinson/Smith, Bateman and several others would have NFL teams breaking down the door to sign them. Those guys were just at the START of their careers, not the end.
