One player to watch

One player to watch from each AFC West team in Week 9:

Denver is on a bye this week.

Kansas City: Mike Vrabel, linebacker: Vrabel, 35, played like he was in his prime in the Chiefs’ overtime win over Buffalo. He had 11 tackles in the game. He was all over the field. Vrabel is no longer a dominant tackler, but he is a smart player and expect him to be ready for the Chiefs’ vital game against Oakland on Sunday.

Oakland, Stanford Routt, cornerback: Routt may have a big role for the Raiders. With Nnamdi Asomugha dealing with an ankle injury and Chris Johnson coming back from a concussion, a lot may be asked of Routt against the Chiefs. Kansas City is a run-first team, but Routt may be challenged by Matt Cassel at times.

San Diego, Steve Crosby, special teams coach: Crosby’s unit has to start improving. It has made one silly mistake after another all season. Crosby likely is not going to be fired during the season. He’d likely already be gone if that was the case. But it is his job to ensure his players improve and don’t repeat mistakes. It has to start happening Sunday against Houston.
