"...push the opposing coaches into bad decisions..."
This sounds like a lot of shrieking from the stands that just confuses a bunch of ten-year olds rather than the coaches. What you describe is merely adults working to intimidate and confuse children. It's not a confused coach issue in the least. No time for a coach to say much of anything in a run-down.
My recommendation is that your parents sit still and let the kids play.
And just for the record, it's not the same when the coach does it!
