Defo see your thought process on that, it's the old "South African Bomb Squad" when their Rugby Union side replaced 5 forwards with some giants, they could only operate over 15-20 minutes but that was the aim, to try and hit the opponents when they were tiring. I would like a change to the Laws of the Game that reduces 5 to 4 outfield players with 1 change held back mandatory for GK replacement. I think 5 subs is too much and has taken the workload off players. Even our "tough preseason" they were only playing 45 mins in most of those games. I get not all are going to be quick but all should be able to run for 90 minutes with a 15 minute break in between. When you look at the distance covered for the players that have played 90 minutes, it isn't a lot anywhere between 5-8 miles and some of that will be walking. Realistically a professional should be able to cover 8 miles over 90 minutes !
