As a defensive-minded head coach and co-chair of the competition committee, Jeff Fisher is a leading figure in the move to arm defenses with the technology offenses use to communicate with quarterbacks during games.
Amid league-wide concerns over spying, Fisher said he is "very confident" in the integrity of these communications. Motorola provides headset technology through Control Dynamics Corporation, and teams can choose from 268 million encryption codes each week, the league said.
"We've got scanning devices to determine whether or not there are any irregularities or anything like that," Fisher said. "We spot-check systems and we don't anticipate any problems."
The league oversees unannounced equipment checks at stadiums. "I know they have increased over the last couple years, significantly, and we have not had any problems in the last few years," Fisher said.
Even if the defensive communications system is implemented, teams will continue to use hand signals some of the time, Fisher said.
