I think it would be interesting if you took all kicking out of football. The only way to score is via touchdowns, no Field Goals. No punting, you get four downs and if you don’t convert, the other team gets the ball.
Then if you score a touchdown, I would do the two-point conversion, but with the added incentive of making it so that if you convert, you get the ball back. But you would get it back on your own 20 yard line, so you have the pressure of having to get some first downs, because remember, there’s no punting.
Then you’d have to call it something other than FOOTball. And handball is taken.
