Around the perimeter of the sumo tournament, and occasionally darting through it, are a bunch of greyhounds playing frisbee. This is how touchdowns are scored in modern football. This game should have a new name. Let's call it Sumofrisbee. For real football, one must now turn to the Classic Sports channel on cable.
Real football is a game without sumo wrestlers.
To envision how much the two-platoon rule changed the nature of football, imagine a similar rule change in baseball. On defense, eight speedy, acrobatic fielding experts and a pitcher are on the field. With all those fielding experts arrayed against all those designated hitters, baseball would almost certainly become an unabashed home-run derby. Sort of like the present reliance on the forward pass in Sumofrisbee. Real football will never be back.
