this post by footyfan78 explains the problem and solution.
36 players within 50 metres of the ball, continuous congestion IS ugly football, if you don't think so then you have never watched aussie rules footy, you have only watched AFL.
2 on the bench, 4 interchanges a quarter, problem solvered.
Have your whole list on the bench for all I care. Use them as reserves only. Once you are off you are off.
