I think almost the polar opposite that having extra players and fresher legs means it will just continue in the same vein.
I'm completely stumped by people who disagree with the fact that reducing rotations will return things to a version of footy that is recognisable as footy.
With the benefit of hindsight, the rot started with a single team working out that their star player could play a lone hand version of Richmond's ballistic game style way back in the early 2000s, if he rested on the bench. His numbers didn't go down because of the rest, and his impact on the game actually went up.
Midfield 'Rotations' weren't even in the game until not long after this became apparent to other teams.
Then Midfield rotations became almost entire team rotations by the 2009/11 era (I might be wrong by a year or two... but think commentators talking about 'guys running off the ground after they kick a goal in the modern game', and you'll remember.
Hawthorn resisted big rotations under Clarko when Collingwood were going nuts with it. But he soon realised we also had to embrace big rotation numbers in order to compete.I don't remember which year, but this was an actual story in the press at the time.
Massive rotations led to more of an emphasis on team defence and ballistic running.
Richmond's defensive and offensive game style of 2017 highlighted that increased physical endurance and sustained ballistic attack on the ball and man could actually be more effective than traditional football skills (though they did still have some highly skilled players).
There is a clear advantage for teams playing this game style, so everyone followed to some degree.
The idea that injury will somehow become a factor if the advantage that produced this style of play is removed, is only assuming that guys are going to try and play the same way.
The fact is that if they do, it almost certainly won't work. Players will be gassed by half time. Their team will lose, and we'll likely return to a style of play that asks players to pace themselves or risk blowing themselves up.
And even if sports science gives us far better runners than we've ever had, removing the constant rests will significantly dull the ballistic element of team defence and physical force/rolling mauls we've got now.
Currently, it's a load of crap to watch most games.
It's not even a change either. It's returning to the way it used to be.
