need help with my rookies...

[jumpmaster]

If you are a subscriber to this site you know that I am in the middle of an expirement with a crew. I have a crew of 5 rookies that I am training. We have a full Jr. High schedule and a NCAA white hat as our trainer.

Problem - my rookies are timid with their whistles and their flags. They recognize the situations but are very timid.

Any advice on how to break them of this? I have tried positive reinforcement, asking them to explain what they saw, and telling them to blow their whistle loud enough to hear in the pressbox, but I am still having weak whistles and timid flags.

Thanks in advance!
