ARLINGTON, Texas — Tony Romo is running around and having fun again, and Miles Austin is the reason for it.

Romo returned to his swashbuckling style, keeping drives alive by improvising and turning one near-disaster into a touchdown, and Austin proved his breakout game was no fluke by coming up with big play after big play, leading the Dallas Cowboys to a 37-21 victory over the Atlanta Falcons on Sunday.

With Romo and Austin bringing the offense to life and the defense giving up little more than long drives at the start of each half, the Cowboys (4-2) roared out of their bye with their most impressive win of the season and first against a team with a winning record.

The Falcons (4-2) came in looking to keep pace with the best start in franchise history. Matt Ryan started great, but couldn't keep it up. His streak of 142 passes without a sack ended with takedowns on consecutive plays in the first quarter. He was sacked four times, threw two interceptions and lost a fumble.
