It's going to be old-school football. Any punt longer than 25 yards is a live ball.
Fair catches are history.
The punt returner gets a 5-yard halo to say prayers and catch the ball before getting clobbered. Kissing your sister is not permitted - no ties. At the end of regulation, each team gets one possession starting at the opposing team's 20-yard line. If the first team to take possession scores in three downs, the opposing team will only get three downs to score. The process continues until somebody wins.
