OAKLAND, Calif. — Felix Jones is good. Real good. Look for him to be factor in everything the Dallas Cowboys do on offense in 2009.

That much we found out in the Cowboys’ preseason opener at Oakland late Thursday night.
“Felix is a standout,” owner Jerry Jones said. “It’s exciting to see him make plays.”
Here are some other insights:
TWO TIGHT-END OFFENSE
After much hype in training camp, it was a surprise the Cowboys didn’t open the game in the two-tight end set. Soon after, the formation was in full effect. In succession, Martellus Bennett caught a 7-yard pass, Marion Barber ran for 8 yards and Roy Williams caught an 12-yard pass. Jason Witten finished the drive with an 8-yard touchdown catch.
ROMO AND WILLIAMS
The Tony Romo to Roy Williams era didn’t start well with the first pass being batted down by former Cowboy Greg Ellis. Later, they combined on a 12-yard out route on a timing pattern that netted a first down. The combo then drew a holding penalty two plays later against cornerback Stanford Routt. The duo should be solid.
RIGHT CORNERBACK BATTLE
Mike Jenkins and Orlando Scandrick are competing for the starting job opposite left cornerback Terence Newman. That was before Jenkins and Newman missed Thursday’s game with injuries. Scandrick helped himself with a solid outing. Depth is still a concern.
SPOTLIGHT ON SPENCER
Linebacker Anthony Spencer took over with the man he replaced on the other side of the field. It also didn’t help that Greg Ellis batted down the first pass of the game. As first games go, it wasn’t a good first impression. Many will remember his whiff on quarterback Jamarcus Russell’s 18-yard run.
THE FELIX FACTOR
Felix Jones is the primary difference-maker for the Cowboys’ offense. It’s not just what he does with the ball, but what he opens up with his presence. He had a 14-yard run, was a decoy on Patrick Crayton’s 12-yard reverse and later caught a 9-yard pass on Dallas’ first-quarter touchdown drive.
