I'll only comment from an Australia perspective as i know nothing about SA rugby. From an early age (14/15) the so called better kids get into "the program" and as previously mentioned get coached to play the A, B, C runner game, so they look good, they play the style the ARU scouts want to see so they stay in the program. The number of games they play is reduced, so they don't get burnt out, but they are still flogged at training 3 or 4+ days a week. They are all excellent trainers, are big and strong, have excellent skills at training and play very structured rugby against other sides who are all coached the same way and play with a very similar structure. Unfortunately when they are called on to play actual rugby, with counter rucking, game pace kick and chase, high pressure defense that works hard all the time, etc, their training skills go out the window as pressure is applied. Under commitment at ruck isn't an option, just spinning the ball across the backline or hitting the B runner on the chest isn't good enough, you need to go forward. So therefore they need more time, so everyone sets up deeper and deeper until they have the time they need to do what they have always done. Playing rugby that looks pretty but unfortunately the other team isn't doing that, they are playing and not being able to think of a better word "ugly rugby". IMO we need to stop schools preventing boys from playing multiple games a weekend, I've never heard a boy say (unless injured) I don't want to play tomorrow. Stop the weights programs as 14-18 year olds, there wouldn't be so many injuries if boys looked like boys rather than 23 year olds. Just let them play rugby and learn how to play the game of rugby. There is plenty of time to get big when they have grown up. Then they can play hard rugby as men.
