I have a few myself ..
If they go with the stadium clock idea then the ref doesn't call half time of full time......the clock stops and starts per whatever rules...as in American Football, basketball, Hockey etc....then there would be no bull about to much time or not enough time added.
How about:
No back passes from the opposition half.
Make offside much clearer, say clear daylight has to be seen before offside...not just his elbow offside....this alone will lead to more goals.
Player who commits foul should go off along with the injured player....can somebody tell me the logic of the team committing the foul playing on with 11 men while the injured players team goes with 10 for 5 minutes or whatever. That one has never made sense to me.
And of course if they really are interested in making football fairer...then salary caps.....which will not see the light of day in my life time of course.
