Detroit Lions defensive coordinator Gunther Cunningham says his unit's performance this season could be inspired by the movie "Grey." I've never seen "Grey," nor do I know what it's about. I guess there is a little trickery involved.

Cunningham breaks it down to Detroit Lions.com's Tim Twentyman:

The first two units at both defensive tackle and defensive end for the Lions could probably start on most of the teams in the NFL, which says a lot about their depth. It also speaks volumes to the many ways the Lions can attack teams up front.

One of those methods will be moving players around more than they have in past seasons, especially versatile players like Ndamukong Suh and Nick Fairley.

Defensive coordinator Gunther Cunningham is hoping it makes the Lions less predictable on defense.

“Well, I call it ‘Grey.’ There’s a great movie out called Grey and if you watch it you’ll know what I mean,” Cunningham said. “The wolves kind of trick (the human characters). They trick them, and the ending of it is great. That’s kind of what we’re doing. We started in the OTAs.

“A couple of coaches wanted to wait and I said, ‘Well, 51-percent says you can’t, so let’s start.’ The players really liked it. We’ve got a lot of varieties of those things we’re doing where they’re up and down.”

Detroit could have one of the most-feared lines in the NFL again this season if things fall into place. But that could be said about a lot of teams. Suh has to bounce back from a decent season -- I refuse to call this past year a "sophomore slump." Now that Cliff Avril has signed his one-year deal, the Lions can rest assured that the bookends of the defense will be intact. Watch out for Corey Williams, too.
