A couple of things. If a parent(s) or player(s) wants to dictate practice, encourage them to get a team together once the season is over and run things their way. Until then, you’re the coach, and you will run practice your way. Sounds harsh, but that’s the way it has to be. Because time is at a premium, Rick has structured the R&R is a way where you can practice fundamentals in the context of the offense. Next season during the first day of practice, have everyone get in a traditional lay up line and shoot one lay up. Stop the action once everyone has shot, and announce that is the last offensive drill they will ever do at practice to drill fundamentals not in the context of the offense. Ever. Everything after that will kill two birds; sharpen their fundamentals and master the offense. Those that can do both will maximize their opportunity for playing time.
Read Line and Circle Move are the two actions that give players the most trouble, so be sensitive to that, and start working on those actions early and often. Rick details some scrimmage strategies you might use to stimulate Read Line execution. Change up your drills so the players have to think during a drill and not just “play the drill”. Randomize the defender stepping over the read line. Film the drill and heap heavy praise on the players that cut. You don’t have to publicly scorn those that don’t, keep it positive. Do you have any game footage where other players are cutting? Video review was a integral part of our practice and is a great way of illustrating what you are looking for. Once again, the focus should be on the positive. Playing time is the other way of managing this situation also.
