Only the Jaguars receivers and linebackers have the same position coaches this year as they did last year. Coach Gus Bradley opted to retain Jerry Sullivan (receivers) and Mark Duffner (linebackers).

But for Paul Posluszny and Russell Allen, having Duffner run their meeting room doesn’t mean there won’t be a transition.

Bradley and defensive coordinator Bob Babich have their own playbook and their own teaching methods.

“I think it’s good we have the same coach because we know how to interact with him and we know what we’re going to get from him,” Posluszny said of Duffner. “As far as the technique that we’re going to be using on the field, there are going to be some big differences from last year. We have a lot to learn in a short period of time.”
