1) Tyler Patmon, an undrafted rookie free agent, intercepted two passes (returning one for a TD) and forced a fumble.
Ultimately, the game is about making plays and he provided the coaching staff with several reasons why he should be on the roster, especially at a position where the Cowboys have a plethora of questions.
Tyler Patmon, right, made a number of big plays against the Dolphins, including making two interceptions.
Patmon forced a fumble with a perfect open-field hit at the Dallas 36-yard line, ending one potential Miami scoring drive.
In the third quarter, he intercepted starter Ryan Tannehill's underthrown pass along the sideline at the Dallas 5. Patmon made his biggest play in the fourth quarter, intercepting a swing pass at the Miami 9 and returning it for a touchdown that gave Dallas a 20-11 lead with about seven minutes left.
Each play changed the game, and it will help that Patmon made his first two plays against Miami’s starters.
2) In case you didn’t know it, Dwayne Harris showed why he’s one of the Cowboys’ most valuable players.
He’s a difference-maker on kick and punt returns, the kind of player who will help the Cowboys win a couple of games this season with his work in the return game.
He averaged 38.5 yards on two kickoff returns, including a 50-yard return that he nearly took back for a touchdown. He has outstanding vision and a feel for the soft spots in coverage, and once he sees an opening he attacks it.
3) Right now, safety Ahmad Dixon gets the vote for the player most likely to give Jason Garrett a migraine. Or turn his red hair gray.
Still, there’s something to like about Dixon’s aggressive -- perhaps reckless is a better word -- approach. If it can be harnessed, then Dixon could eventually be a really nice addition to this secondary.
Last week, he didn’t play as punishment for being late to a walk-through practice the day before the Baltimore game. Against Miami, he made a poor decision that resulted in a 15-yard penalty for unnecessary roughness late in the fourth quarter.
On third-and-9 from Dallas' 22-yard line with 2:11 left, Miami quarterback Matt Moore overthrew receiver Matt Hazel near the goal line. Dixon might have been able to intercept the pass if he hadn’t been so intent on punishing Hazel.
Instead, Dixon blasted Hazel in the chest. It was a classic example of hitting a defenseless receiver and drew a penalty.
An incompletion would’ve forced Miami, trailing 20-19, to attempt a field goal and would’ve given Dallas an additional 30 seconds or so to rally had Miami made the kick.
The penalty moved the ball to the Dallas 11 and five plays later Miami scored the go-ahead touchdown.
Key number: 3.4
The Cowboys gained only 110 yards on 32 first-half plays. Tony Romo played the entire first half, so that excuse has been eliminated. The Cowboys didn’t have any pass plays of 20 yards or more or running plays of 10 yards or more, so we shouldn’t be surprised their offense produced just two field goals. More important, they failed to control the line of scrimmage.
Williams is doing his best to make it difficult for the Cowboys to cut him. He finished with 12 carries for 47 yards, a 3.9 yard average per carry, but he’s a more dynamic runner than Joseph Randle.
The problem, of course, is the third running back has considerably more responsibilities than just running the ball since DeMarco Murray and Lance Dunbar will get the vast majority of carries.
Randle is better in pass protection and he’s better on special teams. Randle delivered a big hit on kickoff coverage against Miami. The Cowboys can suit him up and know he has a role; they can’t do that with Williams.
This is the best competition for a roster spot on the team. Each week, Williams makes it more difficult.
He has one more opportunity to sway the coaching staff, but he needs to do it without the ball in his hands.
