GREEN BAY — The Green Bay Packers' defense has been a showcase of versatility throughout training camp, with new defensive coordinator Jonathan Gannon mixing and matching personnel to create different looks. "This has been a cool crew to work with because of the amount of guys that have multiple skill sets. At times during camp, the Packers have had three safeties on the field at once. "Matt and I have had some really good conversations about that. But I think our players have earned the right to play our stuff, get really good at it and go play," Gannon said.
