I am a casual football fan with a layman's level of knowledge of the game. I was cruising the NY Times today and found this article about adding microphones and headsets for players in order to deal with crowd noise. Doesn't sound like a good idea to this Monday morning quarterback.
"With no reasonable way to curb enthusiasm without appearing stodgy, Roger Goodell, the new N.F.L. commissioner, is floating another idea: placing microphones in quarterbacks’ helmets and speakers in the helmets of other offensive players, so that play calls and snap counts can be heard despite the din. Quarterbacks now have earpieces that allow them to hear coaches, but the transmission is cut with 15 seconds left on the play clock."
