So many questions surrounded the Dallas Cowboys as they entered Week 3. With no Dez Bryant or Tony Romo, how would the rest of the team respond? Coach Jason Garrett's mantra of "next man up" played a big part in preparing for the game against the Atlanta Falcons. Backup quarterback Brandon Weeden started for the first time since last season against the Arizona Cardinals, but this outing was much different. He completed 22 of 26 passes for 232 yards. Although he threw one interception and had zero touchdowns, the loss could not be blamed on him alone. The Cowboys played very well in the first half, outscoring the Falcons 28-17; however, the Falcons made a few halftime adjustments that squashed any running game the Cowboys pursued. On the other hand, the Cowboys had no answer for Julio Jones, who ran 164 yards and had 2 touchdowns.  Owner Jerry Jones said after the game that the Cowboys just looked tired in the second half. In typical fashion for this season, the Falcons came back late in the third quarter and won the game 39-28.
