Halftime thoughts: Cowboys rolling

ARLINGTON, Texas -- If you're a Dallas Cowboys fan, only one thing happened in the first half today to make you mad, and it involved a cheerleader. Buffalo Bills receiver David Nelson caught a second-quarter touchdown and then jogged the length of the field to give the ball to his girlfriend, who is a Cowboys cheerleader. The two shared a hug, and some meanies on Twitter started talking about how she should be fired.

Other than that... man, it's been all Cowboys. They've done absolutely everything they've wanted to do on offense. Tony Romo completed his first 13 passes and is 18-for-19 for 237 yards and three touchdowns. DeMarco Murray has 71 yards and a touchdown on 11 carries. They've converted all seven of their third-down chances. All four of Dan Bailey's kickoffs have gone for touchbacks. It's been a dream game for the offense and a pretty great one for the defense, which has tackled well and even been able to contain star Buffalo running back Fred Jackson in the run game and the screen game.

The was one little cause for concern just before halftime, as Murray left the field after his 25-yard run up the left side. The team has made no announcement about his condition, and we'll keep you posted, of course. But assuming nothing bad has happened to the rookie running back, the Cowboys headed into that halftime locker room off as impressive a first-half performance as they've had all year.

Now, some folks here in the press box were saying it reminds them of the Detroit game, which the Cowboys led 27-3 early in the third quarter and ended up losing. So if Romo starts having interceptions returned for touchdowns in the third quarter, maybe there's reason to be worried. But unless the Bills know something I don't, Calvin Johnson's not walking through that door.
