I would imagine it would cut down missing signals a great deal. I've never used them in baseball (though I did use a number system just no wristbands) I have however used them for many years with a no huddle offense in youth football. Way better than signals but football has built in time to read the wristbands baseball doesn't. I don't understand the wrist bands in baseball. A number system that can't be figured out by the other coach is easy enough without the wristbands.
