I played football (soccer for American readers) in a cage when I was younger. My son played in a cage; it was the easiest way for him to access football facilities and play with his mates, without being part of a club.
It’s taken decades for football academies to recognise players learn an entirely different skillset from this way of playing. Cage football was never lauded but ridiculed as not being ‘proper’ football.
What cages do people play in at work that you are ignoring in your learning strategy?
