SEATTLE — Desperate to patch the holes in their NFL-worst run defense, the Green Bay Packers got innovative this season.

They thought inside the box.

At the midway point of the season, after giving up 172 yards rushing in a 44-23 loss at New Orleans, they moved Clay Matthews from outside to inside linebacker for a significant chunk of the snaps.

It was a risky move with the team’s best pass rusher but it paid off.

The statistical influence was dramatic, with the Packers going from 32nd against the run in the first eight games (153.5 yards per game) to sixth in the last eight (86.4).

“I think if you look at the change of where we were in Week 8 and bye week into now, and obviously, statistics will show that we’re moving in the right direction,” Matthews, a former USC standout, said Thursday during a break from preparations for Sunday’s NFC championship game at Seattle.

“Both individually and as a team, a defense really. Obviously, we’re winning games and I’m making plays, so as long as that’s happening, we’re doing something right.”

Opposing teams that can’t slow the run against the Seahawks don’t have much of a chance for victory.

Seattle is heavily reliant on bruising tailback Marshawn Lynch to both hammer a defense and set up passing opportunities.

When the Seahawks played host to the Packers in the Kickoff Opener, Lynch ran for 110 yards in 20 carries with two touchdowns, and Seahawks defensive end Michael Bennett questioned Green Bay’s desire to tackle the back at all.

“Obviously, we were the more physical team today, offensively and defensively,” Bennett said after that Week 1 game. “I saw supposedly some of the best players in the league not want to tackle Marshawn Lynch. Of course, nobody is going to say nothing about that, but I saw a lot of guys whiff on tackles that should have been two-yard gains, and they’re supposed to be the best.”

The Packers had their bye week after their eighth game, and that’s when they made the change, moving in Matthews and Sam Barrington, and moving out Brad Jones and A.J. Hawk. The tweak allowed Green Bay to get its 11 best defensive athletes on the field and spackle holes in the run defense.

Since 2011, Lynch ranks first in the NFL with 24 100-yard games and is the only player during that span to rush for at least 1,000 yards and 10 touchdowns each year.

“We’re going to have to gang tackle,” Matthews said.
