For anyone ready to write off Kevin Williams' NFL career, he responded last week with a 2 1/2-sack game.

And for anybody thinking it might be best for the Vikings to say goodbye to the defensive lineman soon, hold on. Williams, an 11-year veteran who becomes a free agent after the season, wants to return to Minnesota.

"That'd be nice to be back here to play another year or so here and finish out and ride off into the sunset,'' Williams, 33, the longest-tenured current Vikings player, said Thursday.

Williams is making a guaranteed $4.9 million this season after agreeing in April to restructure his contract and save the Vikings about $2.5 million in cap room. He wouldn't say whether he would be willing to take a pay cut to come back.

Nevertheless, a few more games like last week's, and Williams could help his bargaining position. In a 34-27 win over Washington on Nov. 7, Williams had his first multi-sack game since 2009.

But those big plays didn't come at Williams' usual defensive tackle spot. They were at nose tackle, a position the six-time Pro Bowler says he doesn't like.

With injuries sidelining Letroy Guion and Fred Evans, Vikings coach Leslie Frazier started Williams at the nose and moved in rookie Sharif Floyd at defensive tackle. With Guion out again Sunday at Seattle and Evans possibly limited in a return, Williams likely will start at the nose again. Regardless, Williams should get plenty of snaps there.

"It's a little bit different animal in the nose tackle,'' Williams said. "You just don't have much room to play with on the nose tackle. You got to be right on your reads. You're the centerpiece of the defense. You got to try to stay in your gap and cut things off for your defense, and you don't want to be wrong.
