Of greater concern, at least for many on the training level, should be how to teach officials the discipline of a patient whistle with these things, if they really are going to be used. Waiting for the first game to work out the kinks with what I predict will be a the scourge of wide-spread, immediate, impulsive playcalling, that'll be too late. Given that this is totally new territory, this is admittedly a totally unexplored area of concern. One or some of us really ought to dedicate some study to whether this concern is actually valid and come up with training strategies to counter what I fear will be a latent problem waiting in the wings. After years of teaching "patient whistle" with an actual whistle, I'm just not sure I've got it in me to initiate the study and strategies myself.
