IRVING, Texas -- Some thoughts from the first half:
Tony Romo finished 15-of-19 for 166 yards and a touchdown, but he wanted two of those passes back. He missed a wide-open Terrell Owens on a deep ball and threw an interception near the goal line.
Texans left tackle Duane Brown hasn't been able to handle linebacker DeMarcus Ware's speed. Ware used the outside moves early and then beat Brown a couple of times on the bull-rush.
I have no clue why rookie RB Felix Jones sat out the entire first half. I haven't heard anything about an injury. He's just been standing there with his helmet on.
Isaiah Stanback, the former University of Washington quarterback, had looked great on returns, but he just opened the second half with a fumble. He was carrying the ball like a loaf of bread.
Cowboys right guard Leonard Davis and right tackle Marc Colombo have been dominant in the first half.
If I'm a Texans fan, I've got serious concerns about Fred Bennett and Jacques Reeves at cornerback.
Cowboys defensive end Marcus Spears is getting a lot of penetration on running plays and has made two stops behind the line.
