Three players to watch: AFC West

Posted by ESPN.com’s Bill Williamson

Denver: D.J. Williams, linebacker: Williams has basically played a different position every year since he entered the league as Denver’s top pick in 2004. He is excelling in the new 3-4 defense in Denver. Williams plays the role of the “jack” linebacker. He is all over the field depending on the situation. Williams is an athletic, smart player who is a reason why Denver’s defense has been so strong. He’ll need to have another big game against New England on Sunday.

Kansas City: Todd Haley, coach: We’re going off the field for this one as the 0-4 Chiefs play Dallas. The Chiefs have been terrible this season and Haley, a first-year coach, has not been able to spark them. I believe Haley is setting a good foundation. But his team needs to win. Haley has been criticized some in Kansas City for his decision making. It’s too early to call out Haley for his coaching. But he does need to find a way to make some good things to happen in Kansas City. The Chiefs have not been competitive the past two weeks.

Oakland: Richard Seymour, defensive end: Seymour needs to give his battered team a burst as they visit the New York Giants on Sunday. Oakland is 1-3. Most of the Raiders' problems have been on offense, but the defense has been far from great. Seymour has been decent since coming over from New England in a stunning trade a month ago. But he hasn’t been dominant or a defense changer. He hasn’t had a sack in the past three games after getting two in his Oakland debut. He needs to make a difference.

San Diego has a bye.
