MIAMI GARDENS — The Miami Dolphins (0-3) travel to Minnesota (3-0) on Sunday to take on the Vikings, who feature defensive coordinator Brian Flores, the blitz-happy ex-Dolphins coach. He blitzed Tampa Bay Buccaneers quarterbacks 27 times on 37 pass attempts in Week 3.

The Dolphins, of course, won’t have Pro Bowl running back De’Von Achane (knee) and wide receiver Caleb Douglas (right ankle) is questionable.

So there’s even more pressure on the offensive line and quarterback Malik Willis to come up with solutions.

Defensively, the Dolphins, who are ranked 19th in the league, could have a small advantage against a Vikings offense that ranks last in the league.

Here are five things to watch on Sunday:

Dolphins’ defense vs. Vikings’ offense

The Dolphins have an opportunity here. Minnesota wide receiver Justin Jefferson (13 receptions, 179 yards, two touchdowns) is questionable due to an ankle injury, quarterback Kyler Murray (one touchdown, two interceptions, 54.3 passer rating) has been bad and injured, and running back Aaron Jones (203 yards rushing, 3.9 yards per carry) has been OK.

Miami’s defense hasn’t truly limited any offense. The Dolphins allow 28.7 points per game, which is 28th in the league. But Miami remains the only team without a sack. This should be a good matchup.

Dolphins’ offensive line

The Dolphins’ offensive line has a big task ahead in the running and passing games. Minnesota’s defense, which blitzes frequently, leads the league in sacks (14.0) and third-down defense (22.7% of conversion attempts allowed), ranks second in points allowed (13.7 ppg), is tied for third in takeaways (six) and is fourth in rushing defense (85.7 yards allowed per game).

Still, Willis (one touchdown, two interceptions, 74.1 passer rating) must be careful not to try to do too much with his legs or his right arm. He almost has no choice but to allow his offensive line to do its thing. The offensive line had a decent showing last Sunday against the Kansas City Chiefs allowing no sacks, and helping Miami have a season bests in rushing yards (119) and carries (31).

Dolphins running backs

Between running backs Jaylen Wright (three carries, 10 yards) and Ollie Gordon II (20 carries, 48 yards) the Dolphins are in a tough spot. Neither player is an experienced runner and neither is adept at receiving. Wright (stinger/foot), who has value as a kickoff returner, missed the Kansas City game. In his absence Gordon had 17 carries for 41 yards (2.4 ypc) and one touchdown.

The Dolphins could promote running backs Jarquez Hunter or Carlos Washington Jr., and use wide receiver Malik Washington (three carries, nine yards). Miami’s run game ranks 20th in the league with 295 yards and tied for 21st at 3.8 ypc.

Willis must take care of the ball

Willis has three turnovers (two interceptions, one fumble), which isn’t crushing, but also isn’t a good total for three games. Yes, he has two touchdowns (one rushing, one passing) but the turnovers represent missed opportunities for a team whose error margin is razor thin. And his lost fumble was simply a ball that came out of his hand.

In fairness, Willis has made better decisions as the season has progressed. However, being without Achane this week, and possibly without Douglas, could put Willis and the offense at a significant talent disadvantage. Willis must be careful to play within himself.

Untimely penalties

The Dolphins aren’t bad in penalties overall. They’re tied for 11th for fewest penalties (21) and they’re 11th in penalty yards (157). The problem is the timing of the penalties.

There’s been the holding call at the San Francisco 49ers 3-yard line that turned a touchdown opportunity into a field goal. There was the illegal shift against Kansas City that turned a game-tying touchdown to a field goal and a 14-10 deficit. There were back-to-back holding calls in Las Vegas Raiders territory. The roughing the passer on a third down when Kansas City was in its own end zone. The illegal contact penalty that negated what would have been the Dolphins’ only sack of the season against the Chiefs.

On and on it goes. The Dolphins must be better when it comes to untimely penalties.
