Coach
Two thoughts (and a personal aside)...
1. If this is your team you have every right to run cuts the way you think best...using your players to the max of their capabilities. I totally agree with that.
2. You should let the boys know that when the get to HS, things may change and the HS coach may want them to do it differently. You don't want players reacting negatively to HS coaches strategies.
As the aside...I started cutting the ball off the way I do when my team was all of 10 years old. Everybody said it was too difficult, blah, blah, including my asst. coaches. But by the time these boys (the core players anyway) got to 60/90 it became routine. Funny thing, my asst. coaches wanted to do things different because they had a tough time grasping it. I always laughed at that one.
I'm curious what your cut-off system is and how it's so difficult that asst's are complaining? I always assumed it was the same at all levels?
