Patriots DE Ninkovich producing in new position

Then, with less than four minutes left in the game and the Broncos rallying, the linebacker-turned-defensive-end forced Willis McGahee to fumble and the Patriots recovered again.

"That," McGahee said, "changed the game."

New England kept the ball the rest of the way and beat Denver 31-21 last Sunday. For Ninkovich, it was another step forward in his transition to a new position for coach Bill Belichick, who places a premium on having players who can contribute in several spots.

"Just having the versatility helps everything," Ninkovich said, "helps the defense, helps the team, helps me."

He'll have a much different challenge on Sunday in Seattle. Instead of facing the 36-year-old, 6-foot-5 Manning, he'll try to sack the Seahawks' more mobile quarterback, 23-year-old, 5-foot-11 rookie Russell Wilson.

The keys to stopping him are collapsing the pocket so Wilson can't escape the rush, Ninkovich said.

"Sometimes watching the tape you can see that the rush will get to him and he's able to kind of just get around some guys," he said. "It definitely is different (playing against) him as opposed to a guy who's 6-4 that can stand tall in the pocket. He's obviously got to move a little bit to get to some of those windows" where he can have a clear line of vision between big linemen.

Ninkovich's responsibilities are simpler this season at his new position. He rarely has to worry about covering receivers. His job is to beat his blocker and tackle the ball carrier.

But that blocker almost always is bigger than the 260-pound, 6-foot-2 Ninkovich, who usually was blocked by a tight end last season.

"You just have to play with a different type of leverage and mentality, obviously, (when you're) going against a guy that you're giving up a lot of weight to," he said, "but it's all about technique and working your hands and not letting them get underneath you. So being a little bit shorter ... helps you get underneath those guys. They don't like that too much."

Last season, his seventh in the NFL and third with the Patriots, Ninkovich started all 16 games at outside linebacker. He made a career-high 62 tackles, had 6 1/2 sacks, returned one of his two interceptions for touchdowns, forced one fumble and recovered two.
