Dan Quinn contemplated his coaching style and scheme after the Atlanta Falcons fired him following an 0-5 start to last season.

Quinn tweaked his scheme before joining the Dallas Cowboys as their defensive coordinator.

"I wanted to do as big an after-action on my own self to make sure what I could learn from, things that went well and things that didn't go well," he said. "So, I wanted to kind of do a 360 on the whole process first, the scheme side."

In the three months between getting fired and joining Mike McCarthy's staff, Quinn said he stripped down his belief system, determining what would work for defenses in 2021.

"That included defensive cutups from 2013 to 2020, and that brought me into some of the system changes that I wanted to implement on the next lap around," he said. "I didn't want to do just another rinse and repeat. And, so, that was a big piece on what I wanted to do."
