If New England had scored on that last play hail mary pass, would there have been an extra point kicked? That would have changed the point spread result. I imagine, in that case, New England would have just downed the ball rather than risk having it blocked and returned for a tying two points. And in that case, the gamblers would have gone crazy, especially Patriot backers. I submit that would have qualified as the biggest and wildest pointspread outcome in gambling history, affecting many millions of dollars wagered.
