Okay then. Two, two minute halves. That's it. But as I suggested earlier, they have to move the goal posts to the sidelines on the fifty yard line and all the players play every down. So, the field is 100 yards wide, not 100 yards long. And, let's do away with kicks. Ref starts each two minute half by putting a ball on each 35 yard line at the middle of the field and blows a whistle. Teams line up on the edge of each sideline and run to recover the ball. No time outs.
