OXNARD, Calif. -- The first weekly stock report of the Dallas Cowboys' 2013 campaign is here. Are you buying or selling?
Dez Bryant: He's been amazing. He's clearly the best player on the 90-man roster and he's catching nearly every pass thrown his way, in tight and loose coverage. The best catch of the first week of practices came in team drills when he covered tightly by Brandon Carr. Bryant turned and caught a Tony Romo pass in the cuff of his arm.
DeMarcus Ware: The defensive end told line coach Rod Marinelli he's healthy and his outstanding work is just 50 percent of what he can do. Marinelli replied that he wants more and more. Ware is beating up tackle Tyron Smith on the pass rush and doesn't appear to have any issues with his surgically repaired shoulder.
DeMarco Murray: Health is a constant issue for the starting running back, but he's running fast, taking some licks and doing what he did last year in training camp -- looking impressive. It will be hard for any of the current backs to overtake his role on the team unless there's an injury.
Ben Bass: The undrafted defensive tackle was moved to end to replace Kyle Wilber with the first-team defense. Bass has impressed Cowboys coaches with his pass rush and his ability to slow down the run.
Eric Rogers: It's very early, but of the backup wideouts, he's been the best. He runs smooth routes and makes the easy and tough catches. He'll get his first big test of camp in Sunday's Blue and White scrimmage.
Miles Austin: While Bryant has been impressive, Austin has gotten off to a slow start. He's had two drops, a fumble and a few mental mistakes. Coach Jason Garrett got on Austin for not lining up wide enough on one play, saying he should know better. Austin is a talented player who should pick it back up.
Interior O-line: Where do we begin? Starting guards Nate Livings and Mackenzy Bernadeau are hurt. The replacements, Kevin Kowalski and David Arkin, are struggling. Rookie center Travis Frederick has been pretty good and very quick, but he's on the ground too much. Phil Costa is doing fine, as is Ryan Cook. But Cook just started practicing after failing the conditioning test.
Jay Ratliff: It's not because of his play; he just hasn't practiced. Ratliff injured his hamstring while passing the conditioning test. The Cowboys were going to limit Ratliff's work after his recovery from a sports hernia surgery, but he's not on the field right now because of a new injury.
Terrance Williams: A third-round pick from Baylor, the rookie wide receiver has a few drops and has been inconsistent. At times you see his speed on deep balls, and he's smooth when he does catch passes. But he needs more work on the details.
Kyle Wilber: The Cowboys moved him from outside linebacker to defensive end and asked him to gain some weight. He's done that, and when Anthony Spencer went down with a knee injury, Wilber moved to the first team. That lasted less than 72 hours. Bass has replaced Wilber as the first-team end. Wilber is with the second team.
