Yep. And even some of the radical suggestions coach’s will still get around. For example 16 a side. What do you think clubs will do ? They’ll just recruit and build with more athletes who can run to defend and that will have other consequences eg perhaps a drop in skill levels.
That seems the most likely consequence of both reducing on-field numbers - and extending the bench for that matter.
More athletes, fewer pure footballers.
Just wish all these professional tinkerers would leave the bloody game alone.
