Quote:Reference the time out call.  Is there any reason in this day and age we rely on red flags for challenges and hearing a coach yell time out in a noisy stadium (or looking back up field when the offense is trying to run a play to see if someone if holding his hands in a T formation)?

 

Coaches (either the head guy or someone shadowing him) should have a button(s) in his hand that signals challenge/timeout on the scoreboard/screens.

 

Use the flags and hand signals if system breaks.
