Why do you think there are too many games? Top clubs have about 50% more players in their squad than they did 50 years ago when they played nearly the same number of games.Getting of the league cup and reduce the league size down to 18 teams would help too.
Also not having 2 legs for knockout ties in European football would be a good idea.
Problem is more games equals more money and that’s why there is too many games
If the issue is damage to players then why not limit the number of minutes played in a season?
