Stock Report: Arkin up and Orton down

GLENDALE, Ariz. -- After three preseason games, the Dallas Cowboys come home. As they rest, we review Saturday's 12-7 loss to the Arizona Cardinals with our weekly Stock Report.

Stock Up

DeVonte Holloman. The sixth-round pick from South Carolina makes plays. He picked up his second interception of the summer near the end zone on a pass from Drew Stanton. Holloman is still learning the way to play linebacker in the NFL, but that's OK, because he just always seems to be around the ball. Holloman had an interception and a quarterback hit against the Cardinals and is securing his spot on the 53-man roster.

Alex Tanney. The young quarterback threw his first touchdown pass, the only touchdown of the day for the Cowboys, and connected on his first 11 throws. The interception at the end of the game was a downer, but he completed 14 of 19 passes for 136 yards.

David Arkin. He was inserted as the starting left guard with Nate Livings and Ronald Leary kept out of the game by knee injuries. The Cowboys did run toward his side, and it appeared he missed a block during a twist, but, for the most part, he played well.

Stock Down

Run defense. The Cowboys' first-team defense did a nice job against the run, but it went haywire afterward. Arizona rushed for 105 yards on 31 attempts and picked up gains of 11, 11, 24 and 10 yards. The Cowboys need to get more physical up front.

Kyle Orton. Orton threw two interceptions, both bad throws, during three offensive drives. It was a much different Orton than the one we saw in Oakland last week, when he made a nice touchdown pass to Cole Beasley. Against Arizona, Orton was 4-for-8 for 36 yards and a 22.9 quarterback rating.

First-team offense. We understand two fumbles occurred after long pass plays to Dez Bryant and Lance Dunbar, but in three possessions, the Tony Romo-led offense didn't produce any points. The Cowboys would have been setup nicely in the red zone if not for the turnovers. The Cowboys didn't do a good job on a third-down short-yardage play, getting zero yards from DeMarco Murray on a run.
