Two seasons ago, Ravens defensive tackle Tony Siragusa deprived the Raiders of a Super Bowl by flopping his 340-pound body on quarterback Rich Gannon in a championship game. Last season, Patriots quarterback Tom Brady stole the Raiders Super Bowl ring by a little known rule called the Tuck.

Time is ticking on the Raiders of the lost clock. It's cost them coach Jon Gruden, who was younger than some of his pupils and was traded to Tampa Bay for a fist full of draft choices. Three starters retired -- guard Steve Wisniewski, linebacker William Thomas and cornerback Eric Allen. So what did the Raiders do? They went out and got older, bringing in ancient stars such as linebacker Bill Romanowski, defensive tackle John Parrella and safety Rod Woodson. For a team that trains in wine country in Napa, Calif., the Raiders may test the adage of developing like fine wine.

Not going to the Super Bowl may turn the franchise into vinegar. They have a dozen starters in their 30s, half of that group in their mid-to-late 30s. It's time. With the franchise being more than $50 million over next year's cap, this is the year for the Raiders to prefect their lost art of winning Super Bowls. To eliminate distractions, Raiders boss Al Davis endorsed a six-year, $54 million extension to 37-year-old quarterback Rich Gannon.

Still, a coaching change and the team's ability to stay healthy despite their aging bodies will determine if they can achieve their goal.

Man in the spotlight
None of the new coaches faces the pressure of Bill Callahan. After all, no other coach has to win a Super Bowl to win over fans. The Raiders let Gruden go because he wouldn't sign an extension and was becoming too popular among fans. The Raiders believe the players are more important than the coaches, so it's up to Callahan to keep all the egos together. That won't be easy. Gruden had a knack for adding discipline along with keeping the players loose and well-coached. Callahan has head coaching skills, but he doesn't have the luxury to make mistakes on the job.

Key position battle
Tory James has the skills to be a starter, but he will have to hold up for 16 weeks to prevent Phillip Buchanon from beating him out. Buchanon is the classic Raiders cornerback, a brash, outspoken coverage fiend who loves to get in the face of receivers. James was one of the league's better third cornerbacks, but he has to start the season as Allen's replacement. For the Raiders defense, cornerback is one of the most important positions.

Injury update
The Raiders feel good about how their battered offensive line survived last season. Center Barrett Robbins appears to have recovered from his knee reconstruction. Right tackle Lincoln Kennedy had shoulder surgery. Left tackle Barry Sims has had two foot surgeries in two years. Guard Frank Middleton had operations on both feet. But the offensive line is in better shape than the defensive line. End Trace Armstrong is coming off an Achilles tendon tear and is expected to participated in 35 percent of the plays. End Regan Upshaw blew out a knee in minicamp, but he could be back in October, which might be adventurous. Backup quarterback Bobby Hoying is struggling coming off elbow surgery but Marques Tuiasosopo is ready to take over as backup.

Rookie report
Buchanon is the only draft choice expected to see major playing time. First-round linebacker Napoleon Harris will learn behind middle linebacker Greg Biekert but shouldn't knock him out of a job unless there is an injury.
