It may not happen immediately, but I actually expect this defense to create many more turnovers and sacks than under Rex. They didn't create many turnovers under Rex (I think only 18 last year?), and that is a staple of McDermott's defense. He loves creating turnovers. Carolina was near the top of the NFL in turnovers in many of McDermott's years there. Even last year with a bunch of rookies in the secondary they were tied for 4th. 2015 they were 1st. 2013 they were 5th. They were near the top of the NFL in sacks many years too, IIRC.
