The 2013 defense ranked second in the NFL to Seattle and last year's defense that got Carolina to Super Bowl 50 ranked sixth.
McDermott has been able to maintain that excellence despite turnover. In 2014, he had to replace all four of the defensive backs that started the final game the previous season.
After the first game of the 2014 season, Pro Bowl defensive end
Greg Hardy sat for the rest of the season to deal with his domestic violence case.
Last season, McDermott adjusted for seven games when starting end
Charles Johnson was on injured reserve and for three games when Kuechly was out with a concussion.
The challenge this season is replacing three-fourths of the starting secondary, including Pro Bowl cornerback
Josh Norman.
But with a front seven that ranks among the best in the NFL at pressuring the quarterback and stopping the run, there's no reason to think this can't be another top 10 unit.
"Coach McDermott's strength as a coach right now, without a doubt, is his ability to motivate guys and keep guys tuned into what we're trying to do as a football team and as a defense," Davis said.
McDermott's strength also is getting the most out of what some might consider second-tier players. He's done it time and time again, particularly in a secondary that has been a revolving door the past four seasons.
He understands how to get the most out of those players because he once was one of them.
So yes, he was a walk-on at William & Mary that became a team captain.
"We call it being wired like a Panther ... the Panther DNA," McDermott said. "What I look for are guys that work hard, have a great work ethic and embrace that underdog mentality a little bit. And certainly there is no substitute for toughness."
Toughness is what enabled McDermott to become a star wrestler. So yes, that's true as well.
McDermott learned the basis for his 4-3 defensive philosophy from one of the best, former
Philadelphia Eagles defensive coordinator
Jim Johnson. It's a system based on pressuring the quarterback in the pass and run game.
But McDermott, 42, has taken Johnson's scheme that involved sophisticated zone blitzes and put his own stamp on it. He hopes one day that will land him a head coaching position after interviewing for several jobs the past two years.
"I don't interject as much as people think I do," said Carolina coach Ron Rivera, a former defensive coordinator. "The big thing for him is he's kind of developed his own personality.
"You can't reflect on where you've been and what they've done. You've got to grasp your opportunity and make it your own. He's done that."
McDermott calls his defense player friendly. He builds around the strengths of players and finds ways to cover up weaknesses. He doesn't try to turn a 3-4 end into a 4-3 end.
"That's important, rather than tying them up with intricate schemes and things," McDermott said. "We can certainly do that. It's like the game of chess. But at the same time a player has to be able to execute and play fast and be fundamentally sound."
That's why McDermott is comfortable with the potential of starting rookies
James Bradberry and
Daryl Worley at cornerback. Through an intensive evaluation process the organization determined months ago the second- and third-round picks had the physical tools to play immediately.
"You learn to adjust and adapt," McDermott said. "That's a sign of a good football team, where we can adjust and adapt to our surroundings."
Getting players such as Bradberry and Worley to believe in themselves is part of the adjustment process. That's why McDermott believes games such as "Two Truths and a Lie" are important.
His players have bought into it.
"You get to know not just the football player, but the man off the field," linebacker
A.J. Klein said.
Apparently, McDermott is as creative with his lies as he is with his schemes.
"He makes up some pretty good stuff," Klein said.
Asked what his two truths and lie were this year, McDermott smiled and said, "I haven't done mine, yet."
So no, McDermott didn't carve bears out of tree stumps.
Sean McDermott believes defenses are about more than X's and O's and rely on trust among players. That's where a classic icebreaker game comes in.
