1. Put only CHAMPION teams in playoffs, not wild card teams. If odd number of leagues, figure out a way to make them even number. Duh.
2. Take the foot out of football point scoring. Extra points are virtually automatic as are field goals within 30 yards; even 50 yarders are becoming expected.
a. For extra points, teams should get one chance to score from the 10-yard line for one extra point, or one chance to score from the 30-yard line for two extra points.
b. No more field goals, period. The game is about getting the ball over the goal line carried or caught by a human. Extra points and field goals are just tie breakers. In the unusual game where field goals are only score, that basically shows which team has the best kicker, and it's an 11-person team.
c. Kickers only kick off or punt. That's enough involvement to retain the name Football. American football is not Euro football, which is ironically called soccer which sounds more like what American football teams do to each other.
