OWINGS MILLS, Md. -- The Baltimore Ravens are using colorful gamesmanship in trying to disguise their defensive signals from the sidelines.
Three assistant coaches -- each wearing a green, yellow or red hat -- relay the calls to the field. It's unknown whether all are sending in signals to their specific position group or if two are conveying "dummy" calls.
If that wasn't enough subterfuge, the Ravens' injured and practice squad players stand behind those assistants and hold towels over their heads to shield them from the opposing coaches' box behind them.
"It’s kind of one of those things we probably don't talk about," coach John Harbaugh said.
