Tim Heitman-US PRESSWIRE

it is about time to place a bow on this preseason for the Cowboys.

We are below the 2 minute mark and the Cowboys have this game well in hand.

Lance Dunbar and Phillip Tanner did very well for the Cowboys rushing attack tonight.

Not much seen from the receiving corp but I would not place all of the blame on that unit alone. The quarterback play was subpar and the offensive line was shaky.

So after this showing by Dallas, with only one starter playing in Phil Costa, how do you feel about the Cowboys entering the season?

Nothing from linebacker Adrian Hamilton tonight. He has not recorded a tackle or a sack.

Hamilton can be impactful without scoring a tackle but he needed a strong showing in the last preseason game.

I like Hamilton and his potential but the Cowboys cannot afford to wait on him to mature this season.

Would not surprise me if he is cut.

SCORE UPDATE

The Cowboys Dan Bailey boots a short field goal to extend Dallas' lead.

Dallas 30

The Cowboys are in striking distance again as Rudy Carpenter is leading a drive toward another touchdown or field goal.

So far Carpenter has looked just as average as McGee.

He is four for eight with 48 yards and no touchdowns or interceptions. He just hasn't look that great tonight but the offensive line hasn't either.

I can still see Carpenter beating McGee out for the last quarterback spot. McGee hasn't shown the team much and at least there is an opportunity to possibly grow Carpenter in the offense.

Matthew Emmons-US PRESSWIRE

If I had to name a player of the game, defensively, I would give it to Alex Albright.

He's been all over the field, placed an enormous amount of pressure on the Dolphin's pocket and got a sack in the process.

Albright recorded eight solo tackles and 11 total for the night.

A great night for Mr. Albright.

Tim Heitman-US PRESSWIRE

Dunbar is returning punts and kick-offs for the Cowboys. So the coaching staff see's something in him that they like.

He is either a practice squad player or another team will use his services.

A great night for Dunbar's future.

Matthew Emmons-US PRESSWIRE

David Arkin just had two very bad plays in a row.

He was bull rushed by a Dolphins lineman that led to a throw away pass by Rudy Carpenter. Arkin never seemed to get his feet set and he was on the ground within seconds of the ball being snapped.

On third down, the offensive line didn't give Carpenter much time to throw and Arkin was beat again for a sack.

Hopefully those two plays won't doom his roster spot but they looked really bad on camera.

Tim Heitman-US PRESSWIRE

It is the end of the third quarter and the Cowboys are up 27-13.

Dunbar is doing his best to either make this Cowboys team or another NFL team looking for a running back.

He's averaging 10.2 YPC and has eclipsed the century mark on the ground.

Tim Heitman-US PRESSWIRE

Quarterback Pat Devlin has given the Dolphin's offense a nice shot of adrenaline.

Miami is on the goaline as Delvin has gone 4/5 with 46 yards and a rating of 105. A much better showing than Matt Moore.

UPDATE: Delvin led the Dolphins on an 89 yard scoring drive that ended with a Lamar Miller one yard touchdown.

Dallas 27

Miami 13

Tim Heitman-US PRESSWIRE

If one had to make a decision today to keep Dunbar or Tanner, which would you choose?

Dunbar's stats look great tonight because of his 58 yard touchdown. Not to mention he's playing against inferior competition.

Tanner is still paying his dues and deserves a chance to fully prove himself. Tanner is a better blocker and has more experience.

Just watching this game, Dunbar would be the favorite. In the long run, I would choose Tanner with Dunbar finishing a close second.

Tim Heitman-US PRESSWIRE

Lance Dunbar just earned a spot on the practice squad.

He just broke for a 58 yard touchdown to increase the Cowboys lead to 27-7.

He broke a nice amount of tackles, showed good vision and used his cut back lane very nicely.

Tim Heitman-US PRESSWIRE

The Cowboys linebackers look pretty good to me.

Orie Lemon, Baraka Atkins, Victor Butler, Eddie Whitley and Alex Albright have shown fantastic potential tonight.

Matt Moore is still struggling and the Cowboys second and third unit defense just forced another Dolphins punt.

Steve Mitchell-US PRESSWIRE

If Matt Moore is going out for a roster spot, he's doing a lousy job of saying he wants it.

Moore's stats for the night read like a junior varsity quarterback.

3/11 34 passing yards 1 interception.

Tim Heitman-US PRESSWIRE

So at halftime the Cowboys have a very nice lead over the Dolphins.

Dallas 20 Miami 6

The Cowboys scored 20 unanswered points in the second quarter as Dan Bailey, Orie Lemon and Phillip Tanner all put points on the board.

Tanner and Dunbar did a very nice job of making strong cases for themselves in the first half. Tanner had almost 50 yards and scored a touchdown.

Orie Lemon made his presence known by picking off Matt Moore and returning it for a touchdown. Victor Butler put Moore down on the ground for a sack and the secondary has held the Dolphins to just 56 yards passing.

We should have an opportunity to see Rudy Carpenter in the second half.

Kelley L Cox-US PRESSWIRE

With just 20 seconds left in the first half, the Cowboys are in striking distance of making another score before the halftime bell.

Tight end James Hanna has two key catches on this drive that has led to a possible touchdown for Dallas.

Danny Coale is showing his athleticism and the receivers are fighting just as hard as the running backs.

Kirby Lee-US PRESSWIRE

So on fourth down and four yards the Dolphins decide to try for it and they are rebuffed.

The Cowboys take over on downs with about 1:30 seconds left to go.

Miami advanced the ball pretty well but the Cowboys defense stiffened at the right time.

After a seemingly shaky start, Dallas is looking much better.

Tim Heitman-US PRESSWIRE

With two minutes and 30 seconds left on the clock, the Dolphins are trying to mount a drive before the half begins.

The two Cowboys running backs have been pretty impressive so far. Take a look at their stats below.

Lance Dunbar: 5 carries 27 yards

Phillip Tanner: 9 carries 48 yards 1 touchdown

Tim Heitman-US PRESSWIRE

Dallas has the ball at the goaline and waited three downs to score a touchdown. 

Phillip Tanner punched it in from three yards out to increase the Cowboys lead to 17-6.

McGee did a pretty good job on that last drive as he's now five for 13 with 83 yards.

Jayne Kamin-Oncea-US PRESSWIRE

One thing that Lance Dunbar cannot say is that he wasn't given a fair shake in 2012.

I keep seeing his number and clear face mask protector. He has five carries for 27 yards, so he's doing well for himself.

Matthew Emmons-US PRESSWIRE

Orie Lemon just did his best Sean Lee impression.

He picked Matt Moore off after reading his eyes on a crossing route.

Lemon returned it for a touchdown to put the Cowboys up 10-6.

Lemon is fighting for a roster spot and intercepting a pass and returning it for a touchdown should go a long way.

Mark J. Rebilas-US PRESSWIRE

Dolphins quarterback Matt Moore was just sacked by linebacker Alex Albright. Can Albright be an impact defensive player for the Cowboys this season?

Tim Heitman-US PRESSWIRE

McGee couldn't get Dallas into the end zone so the team is forced to settle for a field goal.

Dan Bailey makes it a three point game as the Dolphins lead 6-3.

Tim Heitman-US PRESSWIRE

Dallas' offense is threatening to scare. They are deep within Dolphin territory after a first down run by running back Phillip Tanner.

Lance Dunbar is pushing Tanner for the third spot but from my vantage point Tanner has a pretty good hold on it.

So far he has seven rushes for 46 yards.

Tim Heitman-US PRESSWIRE

End of the 1st quarter and the Dolphins are up 6-0 on the Cowboys.

Ogletree has looked good, Victor Butler has made a few plays and we are still waiting for the Cowboys offense to make a move.

Kirby Lee-US PRESSWIRE

Victor Butler is again showing flashes of what he's capable of in the preseason.

He had a great training camp last year but it did not translate to regular season success.

He just recorded a sack but will he show that same fire when the real season starts?
