OK - OK, It's a great idea
I'll defer to your experience that it's "breakthru" technology
so, student managers would pass out new ones each inning
(just be sure coach gets THE update!)
-
at inning, baserunners could just hand 'em off to a base-coach with their helmet
and, used ones would cover the dugout floor
BTW - OUR "walk-up" music makes the ground tremble til the pitcher takes his sign
the catcher, batter, & baserunners would NOT hear a thing
BTW #2 -
the PA guy & fans also make some noise
"huh?? sorry coach "RED RIGHT 88" is NOT on MY wrist!" tho quarterbacks DO wear the "cheat lists", they get the sideline communication by handsigns/touchpoints, not by someone hollering across the field
a wireless earpiece for the catcher, pitcher, & batters/runners might make sense tho
get one for the PU & crew as well, he'd know what pitch was comming, and could have a private channel for "beefs", appeals, to consult with the crew, get more baseballs, or a wet towel
some could use a channel to get his car unlocked & running to the nearest gate
after the last pitch
guess I'm still not sold, unless I'm missing something
