Sometimes, it's how you start. Sometimes, it's how you finish.
And sometimes, such as the case in the Cowboys' 2006 win over the Falcons, it can be both.
Dallas raced out to a 14-0 lead, and then after falling behind 28-21 in the third quarter, reeled off the final 17 points to not only close out the Falcons for a 38-28 win, but an even bigger goal as well.
The Cowboys clinched a playoff berth for the first time in three years, improving to 9-5. The Cowboys would eventually finish 9-7 and earn an NFC Wild Card Spot.
But the Cowboys got off to a fast start thanks to a touchdown by Terrell Owens and then an amazing interception by DeMarcus Ware, who snatched the ball in mid-air from Michael Vick, and then outraced him to the end zone for a 41-yard touchdown.
Vick led the Falcons back with four touchdown passes, including a short scoring strike to Justin Griffith that gave Atlanta the 28-21 lead early in the third.
But Romo switched the attack to a ground game that featured Marion Barber, who scored a pair of touchdowns to put the Cowboys in the lead for good.
The Cowboys defense locked it down in the second half, totaling four sacks, including 1.5 from rookie linebacker Bobby Carpenter.
