Rob Ryan said his last two years as the Saints' defensive coordinator were "a waste of time" because he was "sitting on my hands" when New Orleans decided to try to copy the Seattle Seahawks' scheme.
"There are two years that don't have my signature on them, and it's the last two years in New Orleans. And that's just the truth," Ryan said during an interview with The MMQB.
Ryan, who was fired by the Saints last November, said his biggest regret was that he didn't speak up to coach Sean Payton when New Orleans changed its scheme after a successful 2013 season.
