Yes but again the limiting factor is the GK. Many teams on the boys side may not give them the goalkicks until U15. Even when you do it give to them, there's no training as to when they should switch long/short and how to make that judgment. The only time my son ever got any such training was when he was the alternate GK on the club's adult UPSL team.
Ooooff...this is my No. 1 pet peeve. So many coaches don't know how to train the rondo or are just lazy. They just do the big circle that gives players on a certain number of touches on the ball. There are so many better ones. The 4 man triangle is a much more excellent way to teach possession in close spaces. The 4v4 rectangle with GKS or backs on both ends is also fantastic. I personally love this one the Galaxy use with the center circle from Aiden Feuer's distribution highlights which teach GKs how to break the line. I want to scream every time I see a coach set up a big circle rondo with 1 ball.
This is again a GK limitation. Even when you hand the goalkicks over to big legged defenders they are often just kicking it with no rhyme nor reason. It takes quite a bit of practice, not to mention field space (how many teams have more than a 1/2 field) to work on. Technically the Gks need to be able to hit with precision which only happens at the higher levels around u16 for the boys. And even on the higher teams, there are tons of alternates that don't seem to be able to do it.
