Four players to watch

Posted by ESPN.com’s Bill Williamson

Denver: Eddie Royal, receiver: The Broncos finally made Royal a big part of their offense against New England. Royal had 10 catches for 90 yards. Seven of his catches were for first downs. In the first four games of the season, Royal had eight catches in Denver’s first four games. The Broncos need to keep getting the ball to Royal on Monday night against San Diego. He makes the offense much better.

Kansas City, Matt Cassel, quarterback: Cassel is quietly putting it together for the Chiefs. In his past three games, Cassel has thrown six touchdown passes and he has not been intercepted. According to ESPN’s Stats & Information, Kansas City coach Todd Haley is showing more trust in Cassel. In the past two games, Cassel has thrown 22 passes of 10 yards or more. In Cassel’s second start, he threw just three passes for 10 yards or more. Watch for Cassel to open it up some more against Washington on Sunday.

Oakland: Michel Bush, running back: The Raiders’ offense badly needs a spark. The team is clearly nervous about letting quarterback JaMarcus Russell try to be the igniter. He threw just 13 times in a 37-point loss last week. With starting tailback out Darren McFadden, Bush needs to find away to get going. He finished last year strong. Now, he has to help Oakland sustain some drives against Philadelphia.

San Diego: LaDainian Tomlinson, running back: The Chargers’ passing game needs Tomlinson to get rolling. Tomlinson had just 15 yards against Pittsburgh after he missed two games with an ankle injury. San Diego has the 32nd ranked run offense in the NFL’s San Diego’s passing game is excellent, but Denver will stack against the pass if Tomlinson can’t find a groove.
