The point is that you don't know just by looking why a high scoring kid or kids is/are repeating a level why that is happening. You can't tell by looking, and I think that it's unhealthy for our children for us to be running around accusing other teams of unethical behavior. I've seen it in baseball. I've seen it in soccer. I've seen it in gym. It never goes anywhere good.
I do know of one sandbagging gym in my area, but I know because the head coach has talked to our head coach about it and has said frankly that the gym owner cares a lot about having the state champion team banners to hang about his gym. Beyond that, I don't know, and really my only view even on that situation is that it ultimately comes back to bite those kids in the butt.
