His next suggestions would be:

a. to use a round ball, because the oval one doesn't bounce consistently, that's hard to plan for.
b. remove tackling as the injury toll is sky rocketing at the moment.
c. have an off side rule in place, as its common knowledge that players that meet front on have less injuries.
d. remove the point posts. People want to see goals kicked in footy, not points.
e. reduce the goals hight and put a net on it. That way his super skilled, well drilled team will have an additional challenge, plus it would enable the players to continue play quicker by having the ball within easy reach.
f. remove handballs. People want to see footy players kick the bloody thing, not move it around by hand in a merry-go-round in the background.
