Radio in Helmet for Defenses Approved

[lwiedy]

"One defensive player will wear a helmet similar to what the quarterback is allowed on offense. Should that player leave the game, a teammate can be designated to also have the device. But only one defender with the device can be on the field at a time"

This sound logistically difficult. Is the second device inactive until a league official activates and who is in charge of notifying that a change is being made? Lots more questions.

It would be hard to imagine that all of this has not been worked out to a "T", but then again wars have been started as the result of poor planning so.... (and I'm not comparing stealing signals with war, so please see the analogy for what it is, not what it isn't, thanks in advance).
