The Miami Dolphins shocked the NFL world again on Sunday, earning a 34-31 win over the Arizona Cardinals. The victory kept them within striking distance of the AFC East lead. But perhaps the best news coming from the win remains the emergence of Tua Tagovailoa.

This win propelled the Dolphins into the AFC playoff picture, despite football pundits once again picking against them. The Dolphins have now won four games in a row for the first time since 2016 and their 5-3 record is their best start through the first eight games of a season since 2014.

Here are five takeaways from the Dolphins’ 34-31 win over the Cardinals.

Dolphins Win Over Cardinals: Tua Definitely QB1

So much of the talk in the wake of Miami’s 28-17 victory over the Rams last week circled around Tagovailoa’s statistical performance. People clamored for more from the rookie. Dolphins offensive coordinator Chan Gailey pared down the game plan once Miami’s defense took control.

Against the Cardinals, though, Tagovailoa answered the lingering questions. He completed 20-of-28 passes for 248 yards and two touchdowns. He also ran the ball seven times for 35 yards in this come-from-behind victory.

Tagovailoa authored an impressive 10-play, 93-yard game-tying drive in the fourth quarter of this one. He connected on all five pass attempts during the drive, including a 14-yard strike to DeVante Parker to convert on a third down from deep in Miami’s territory, as well as an 11-yard touchdown to Mack Hollins. Tagovailoa picked up 23 yards scrambling, too, including a six-yard dash to pick up another key third down.

And after the Dolphins defense stuffed a fourth-and-1 attempt by the Cardinals, Tagovailoa maneuvered the team into field goal range for the win. His performance wasn’t perfect, but it was a welcomed sight for the QB-starved ‘Phins.

Jason Sanders, Best K in Franchise History

Tagovailoa set up Jason Sanders for the 50-yard go-ahead field goal with 5:15 left in the fourth.Sanders netted his 20th consecutive made-field-goal with the game-winner. The kick broke the previous team record of 19 straight makes, set by Olindo Mare in 1999. It was the fourth game-winning kick of his career.

Sanders set a new career-long as well with his 56-yarder to end the first half. He became the first kicker in Dolphins history to make two 50-plus yard field goals in the same game.

Sanders now stands as the most accurate kicker in franchise history. He’s made 86.6 percent (58-of-67) of his career tries.

The rest of Miami’s Special Teams Unit has performed well, too. Punter Matt Haack ranks fourth in punts pinned inside the 20-yard line and ninth in net punting. Jakeem Grant leads the NFL in punt return yards and has the league’s only punt return touchdown.

Dolphins D Does Enough in Win Over Cardinals

Miami’s main difficulties defensively this season have come against mobile quarterbacks and Kyler Murray proved to be the biggest test thus far. The Dolphins defense came up big early, though.

Emmanuel Ogbah stripped Murray on Arizona’s first possession of the game, and Shaq Lawson scooped and scored from 36-yards out. The Dolphins now have a takeaway in 15 consecutive games, which is the second-longest active streak in the NFL behind Baltimore (21 games).

After that, though, the Dolphins defense struggled to contain Murray. He completed 21-of-26 for 283 yards and three touchdowns. Murray showed his elusiveness throughout, avoiding Miami’s pursuit, gaining 106 yards and a scoring a touchdown.

But in the fourth quarter, the Dolphins defense made the necessary stops.

The Cardinals gained 474 yards of total offense, but just 77 of those came in the fourth. For the game, Arizona piled up an average of 7.18 yards-per-play, but that figure shrank to just 5.13 yards-per-play in their final two drives. That number gets even smaller if you remove Murray’s 35-yard connection to Christian Kirk. Without that play, the Cardinals managed just 3.0 yards-per-play down the stretch.

The Dolphins prevented Arizona from converting any third down attempts in the fourth and stuffed a pivotal fourth-and-1 try to set up the game-winning drive.

Howard’s Not the Answer at RB

The Dolphins entered this one thin at running back. Myles Gaskin landed on the IR earlier in the week and Matt Breida missed the game with a hamstring injury. Jordan Howard got the start for Miami but couldn’t muster much of an attack.

Howard gained just 19 yards on 10 carries (1.9 yards-per-carry), though he did score from two yards out late in the first. All told, Howard played just 21 of Miami’s 61 offensive plays.

Rookie Salvon Ahmedtook the bulk of the snaps at the running back position (28 snaps, 46 percent).Ahmed gained 38 rushing yards in his NFL debut, the most by a Dolphins player in their debut sinceJay Ajayi gained 41 yards on Nov. 8, 2015 at Buffalo.

Miami’s running game needs to improve moving forward. The Dolphins gained 91 yards on 25 carries in the win against the Cardinals, a 3.6 yards-per-carry average, which is just okay. But Miami needs to get that rushing total up over 100 yards-per-game to really maximize Tagovailoa’s effectiveness.

Next week, the Dolphins can add newly acquired DeAndre Washington to the mix. Gaskin will be out at least another two weeks and it’s unclear if Breida will be ready to return against the LA Chargers.

Depth Concerns at WR

When Allen Hurns and Albert Wilson opted out of the season, some viewed it as an opportunity for other players to step up. Unfortunately, missing Hurns and Wilson only started the thinning of Miami’s receiving corps. Without rookie Lynn Bowden Jr. on Sunday, the Dolphins saw Preston Williams leave the game after his 9-yard touchdown catch in the second quarter.

Losing Williams pressed rookie Malcolm Perry in the lineup more than he’s ever been in his short career. Hollins also saw an uptick in snaps.

Grant played 48 percent of the offensive plays and caught four passes for 35 yards. Parker played 90 percent of snaps and led the team with six catches and 64 yards receiving. Even newly promoted rookie Kirk Merritt saw some time.

If Williams’ ankle injury keeps him out an extended period of time, the Dolphins receiving corps is in trouble. Although his skill-set mirrors Parker’s, Williams provides another reliable set of hands for Tagovailoa. Grant should see additional opportunities moving forward. Bowden, if he comes of Reserve/COVID-19 list, and Perry could, too.

Miami awaits the debut of Antonio Callaway, who’s currently assigned to the practice squad but who could see time next week.
