but the problem is the calendar.
If lads can play 52 games a year then make those 52 games for club and 1 other team. club and county/college.
52 games divided by 2 teams = a good season for each team.
52 games divided by 10 teams = a rubbish season.
I'm over simplifying the thing here for illustrative purposes but the point stands, the more teams a lad plays on, the less time each team has with that player and the more rubbish each competition is.
