When the undrafted rookie running back from North Texas got his chance, he gave Cowboys coaches plenty to consider when putting their final roster together.
"I know it was a big day. It was all or nothing for me today. I did what I could do. Hopefully it's enough," Dunbar said. "I was so tired (after the TD) I didn't remember to look at the replay at first. ... It was my first touchdown and it's like a dream come true."
Rapoport: Forward thinking
"It was frustrating at times, but I think we got better every week," Tannehill said when asked to evaluate his preseason. "It was a matter of not making the same mistake twice, and I think we did that as an offense. ... We just have to put it all together."
Miami (0-4) finished its preseason winless under new coach Joe Philbin. The season opener is Sept. 9 at Houston.
Two years ago in another preseason finale against the Dolphins, McGee passed for 304 yards while going all the way in the victory that probably assured him the spot as the team's third quarterback that season. The fourth-round pick in 2009 has played in only three regular-season games with one start.
With Kyle Orton signed during the offseason to be Romo's backup, Dallas likely will carry only two quarterbacks on its 53-man roster that has to be set by Friday evening. Plus, McGee is no longer eligible for the practice squad like Rudy Carpenter (4 of 10 for 48 yards) would be.
When they get to their Valley Ranch practice facility Thursday, it will be essentially a Monday of game week.
Pro Bowl receiver Miles Austin didn't play in the preseason because of hamstring issues, and receiver Dez Bryant was held out for the second straight game because of right knee tendinitis. Both are expected to be ready for the Giants, though Pro Bowl tight end Jason Witten (lacerated spleen) is less certain for the unprecedented Wednesday night opener.
"We moved the ball early, we've just got to capitalize when you're down in the red zone," Tannehill said. "You can't stall out on the 3 yard line. ... We realize we've got a long way to go and have a lot of work to do, but we're excited about the opportunities that we have."
Moore was only 4 of 12, including the pass over the middle early in the second quarter that Lemon picked off and took into the end zone for a 10-6 lead.
Dallas cornerback Lionel Smith sustained a concussion, and offensive lineman Daniel Loper tweaked a hamstring. Derrick Dockery started at left guard, and got in a few plays before leaving to catch a flight to Washington D.C. to attend a family funeral.
