NFC West links: Cards' James suspended

Arizona Cardinals

Cardinals running back Javarris James has been suspended for the first four games of the 2013 season for violating the NFL's policy and program for substance abuse, a league spokesman told NFL.com's Ian Rapoport.

Say cheese, Bruce Arians. The Cardinals' new coach takes his official headshot.

Two Cardinals -- Calais Campbell and Dave Zastudil -- make the cut for USA TODAY Sports' 21st annual All-Joe team.

San Francisco 49ers

Which team is more popular in the San Francisco area -- 49ers or Giants? Ann Killion discovers there's a passionate group of fans who feel strongly about their Niners.

“I’m not just a pass-rusher, I’m an all-around player. What I’m trying to do is establish myself as one the best players, not just the best pass-rusher,” said Aldon Smith, who told 49ers.com's Alex Espinoza that he expects bigger and better things for San Francisco in 2013.

Tom Gamble, the 49ers' director of player personnel, accepted a similar position Wednesday with the Philadelphia Eagles, and the San Francisco Chronicle's Eric Branch says the timing of Gamble's departure isn't ideal for the Niners.

Seattle Seahawks

The Seahawks have hired Travis Jones as the team's new defensive line coach.

Monte Kiffin knows an aggressive secondary when he sees one, and the new Cowboys defensive coordinator plans to use Seattle's defensive scheme as a teaching tool in Dallas. On the offensive side, the Tennessee Titans will examine Seattle's offense for ideas to help out quarterback Jake Locker on zone reads.

St. Louis Rams

At age 41, Tim Walton is on the fast track, but the Rams' new defensive coordinator is not an overnight sensation, says Jim Thomas of the St. Louis Post-Dispatch. Columnist Jeff Gordon says Walton is an "excellent fit" for coach Jeff Fisher's team.
