ORCHARD PARK, N.Y. -- Fred Jackson has the production to show he deserves to be regarded among the NFL's top-tiered running backs, and the respect of his Buffalo Bills teammates.

"He's the heart and soul of this team," is how left tackle Demetrius Bell put it.

The only thing missing, which Jackson acknowledges has left him "annoyed," is a new contract to go with it.

Two games into the season, the only place the NFL's current leading rusher is not making headway is with the Bills front office, where Jackson says he's gotten nowhere in a bid to renegotiate the final two years left on his contract. That includes this season in which he's set to make a base salary of $1.75 million, making him the 10th-highest-paid player on the team.

"We've approached them, and it's not gone the way we would've liked it to," Jackson told The Associated Press prior to practice Wednesday. "I'm annoyed by it. I've been playing at a high level for three straight years now. I would like something to be done about it this year. I want something done that's fair for myself and the team."

General manager Buddy Nix declined to comment, citing a team policy from discussing football business.

Unhappy as he might be, Jackson stresses he's not letting off-the-field issues distract him from what he needs to do come game time.

"Not at all. I'm going to play football," he said. "I come to help this team and get wins. And that's what I'm going to continue to do."

Jackson's gotten off on the right foot.

His 229 yards rushing lead the league, and he ranks fifth in averaging 6.5 yards per carry. Just as important, he's played a key role in helping the high-scoring Bills get off to a 2-0 start as they prepare to host AFC East rival New England (2-0) on Sunday.

Jackson had 112 yards rushing, including a 24-yarder that set up a touchdown, in a 41-7 season-opening at Kansas City.

He followed that up with a 117-yard, two-touchdown outing that sparked Buffalo's five-touchdown second half eruption in a 38-35 comeback win over Oakland last weekend.

It was a performance that caught his teammates' attention.

"We don't win that game without Fred Jackson. Bottom line," linebacker Andra Davis said, noting how Jackson opened the surge with an electrifying 43-yard touchdown run 1:34 into the third quarter. "Fred is the guy. It's good to see a guy like him get the respect and attention that he deserves. If anybody deserves it, he definitely deserves it."
