I would watch soccer again if they made the goals six inches bigger all round. When the game was invented people were about 4 inches shorter. More goals equals more fun.
I would watch tennis more if they returned to the old wooden raquets on clay courts. More skill and no more power game and boring tennis.
I would never watch basketball but I reckon it could be improved by making the basket 3 feet higher.
In Rugby league and Union I think at least one player needs to be removed because they are so athletic now they cover the field too much.
Aussie rules should take about half the team off.
NFL should make one team do attack, defence and special teams like every other footy game.
You tell the young people this today and they wont believe you. (appologies to the 5 yorkshiremen from Monty Python.)
