Most sports are the same basic game: "get the ball in the net" or "get the ball over the net". They all have essentially the same rules about offisides, out-of-bounds and interference. Football and baseball are different. Baseball is "Hit the ball with a stick and run to safe." Football is "Carry the ball to the other end of the field." Not judging, but if someone explained that to me as a kid, I would have been more interested in football.
