Rookie Lance Dunbar rushed for 105 yards, including a 58-yard touchdown, and Dan Bailey made three field goals in a 30-13 win over Miami in the preseason finale Wednesday night at Cowboys Stadium.
The final roster cutdown is Friday. Dallas opens the regular season at the New York Giants next Wednesday.
"A lot of guys got a chance to play in the early part of the ballgame," Dallas coach Jason Garrett said. "I think for most part they did a good job. Dunbar ran the ball really well. He showed his lateral quickness and burst through a hole and obviously made big runs. He's a tough guy, not afraid to stick it up in there.
"There were a lot of good things. Those are just initial impression from the sidelines. I feel good about how those guys played. We have a lot of cleanup. The execution, we've got to get better and clean up obviously. They're playing with the right spirit and mentality."
In the battle for a backup running back job, Dunbar, second-year man Phillip Tanner and rookie fullback Jamize Olawale had strong games. Dunbar and Olawale played at North Texas.
Dunbar had a 27-yard punt return to go along with his 105 yards. Tanner had nine carries for 48 yards and a touchdown. Olawale had seven carries for 53 yards with a long of 24 yards.
Stephen McGee completed nine of 18 passes for 124 yards.
"He did a good job once we got going a little bit on offense. We were trying to be balanced early on. Once we started throwing, he started making some plays. You could see him getting a little rhythm," Garrett said. "He can make some plays with his feet. That's a good trait for a quarterback to have. He had a pretty solid first half."
The Dolphins opened the scoring when Dan Carpenter made a 21-yard field goal after a flag-filled 73-yard drive for a 3-0 lead.
Teddy Williams fumbled the ensuing kickoff and the Dolphins recovered at the Cowboys’ 33.
Four plays later, Carpenter made a 53-yard field goal to make it 6-0 at the end of the first quarter.
Dallas countered with Dan Bailey’s 30-yard field goal and followed with a 25-yard interception return for a touchdown by linebacker Orie Lemon to take a 10-6 lead with 11:27 left in the half.
"Orie Lemon made a huge play in the game," Garrett said.
After forcing a Miami punt, the Cowboys marched 80 yards for a touchdown. Phillip Tanner scored on a 1-yard run to make it 17-6 with 4:43 left.
On the final play of the half, Bailey made a 30-yard field goal to extend the lead to 20-6.
The scoring continued in the third period when rookie Lance Dunbar scored on a 58 yard run to push the lead to 27-6.
Miami rookie Lamar Miller scored on a 1-yard run.
Dallas closed out the scoring in the fourth quarter with another Bailey field goal, this from 27 yards, to make it 30-13.
"We'll go back and watch the tape as quickly as we can tomorrow and continue to make those evaluations," Garrett said. "We'll see how all this plays out."
