MIAMI GARDENS — Predictably, the rebuilding Dolphins lost at San Francisco, 35-13, on Sunday and fell to 0-2. And in what’s becoming even more predictable, the Dolphins had no pass rush, a slew of unfortunate penalties (many by the offensive line) and sloppy special teams play.

Dolphins coaches must be better in teaching the basics, and players must be better in taking those lessons to the field. We understand this is a rebuild, so that situation is taken into account on the report card. There will likely be a few more of these types of games this season. At the same time, there’s no excuse for not controlling what’s controllable (penalties, special teams errors), so to speak.

The Dolphins showed their youth and inexperience against the 49ers, and they’ll have to mature quickly because Kansas City, which has won two of the past four Super Bowls, comes to town this week.

Here’s the report card from the San Francisco game.

Run game: D

Running back De’Von Achane led the way with 20 carries for 74 yards (3.7 yards per carry), and the Dolphins rushed 29 times for 102 yards (3.5 yards per carry). We expect more from both Achane, a Pro Bowl selection last season, and the offensive line, which is battling ineffectiveness and penalties. Miami was 13th in rushing last season at 120.2 yards per game. Miami is currently 26th at 88.0 ypg. If the Dolphins can’t run the ball, the rebuild will never get going. The Dolphins, who rushed for 84 yards on 20 carries in the first half, didn’t have a rushing touchdown and their longest run was 8 yards. None of that is good enough. Left tackle Patrick Paul got a good run-blocking grade (82.0) from Pro Football Focus.

Pass game: D

Quarterback Malik Willis (14-of-23, 197 yards, one touchdown, no interceptions, 103.0 passer rating) showed promise once again. His numbers were inflated by that 77-yard touchdown pass to wide receiver Ryan Miller, a special teams ace, in the fourth quarter when the game was decided, but whatever. It was a nice throw, catch and run. Willis was sacked four times and was constantly under pressure. Pass protection must improve. Center Aaron Brewer (32.5), and guards Kadyn Proctor (39.1) and Jonah Savaiinaea (46.1) received poor pass-protection grades from PFF. Wide receiver Malik Washington (four receptions, 43 yards) was solid again, while rookies Caleb Douglas (two receptions, 19 yards) and Chris Bell (no receptions in 24 snaps, which was 41% of the offensive snaps) looked like, well, rookies.

Run defense: C+

The 49ers rushed 27 times for 95 yards (3.5 ypc) and three touchdowns. Running backs Kaelon Black (seven carries, 25 yards) and Christian McCaffrey (10 carries, 23 yards, two touchdowns) didn’t do major damage. Dolphins rookie linebacker Jacob Rodriguez (eight tackles, two in the first half) was so-so. Rookie safety Michael Taaffe (team-best nine tackles) was hot and cold. The front seven was OK, nothing spectacular.

Pass defense: F

Quarterback Brock Purdy (20 of 22, 287 yards, two touchdowns, no interceptions, 149.1 passer rating) surgically dissected the Miami defense in the same fashion Las Vegas quarterback Kirk Cousins did a week earlier. The Dolphins had no pass rush and the secondary had loose coverage combined with missed assignments. The 49ers receivers were wide open all day. Tight end George Kittle had four receptions for 80 yards and a touchdown, and McCaffrey had four receptions for 43 yards. Wide receiver Mike Evans had three receptions for 54 yards; wide receiver Demarcus Robinson had three receptions for 34 yards. Dolphins Rookie cornerback Chris Johnson (one tackle in 42 snaps, or 81% of the defensive snaps) was OK but seemed to struggle against the run.

Special teams: F

There were two major errors: Kicker Riley Patterson missed a 51-yard field-goal attempt wide right, eliminating the chance to take a 3-0 lead, and counter Bradley Pinion dropped a snap for an 11-yard loss that led to a 49ers touchdown. Worse, kickoff returner/running back Jaylen Wright, who had a 36-yard kickoff return, left the game with a stinger in the second quarter and didn’t return. Running back Ollie Gordon II had a running-into-the-punter call that was negated by offsetting penalties. Special teams have been ragged, as expected.

Coaching: D

The penalties and mistakes repeated from Week One, and coach Jeff Hafley, offensive coordinator Bobby Slowik, defensive coordinator Sean Duggan and special teams coordinator Chris Tabor must be better teachers. This is a young and inexperienced team, which means mistakes will be common. However, coaches must greatly reduce things such as missed field goals, blown coverage assignments and penalties. The pass rush suffers from a lack of talent, but the penalties and blown assignments occur due to a lack of focus, and that reflects on coaching.

Stock up: QB Malik Willis

Willis, who has made good decisions overall in two games this season, continues to give solid performances that tease about his future, and at this point there’s no reason to think Miami will need to use its first-round pick on a quarterback. Miami might opt to draft a quarterback in the second or third rounds to compete with Willis in training camp, but at this very early point it seems Willis will be the Dolphins’ starting quarterback next season.

Stock down: RT Austin Jackson and OL

Granted, Jackson opened the season against two All Pros in Las Vegas edge rusher Maxx Crosby and San Francisco edge rusher Nick Bosa. But as Jackson said, he must be better especially when it comes to penalties. In the bigger picture, the offensive line, the biggest disappointment on the team so far because of the expectations, must be better in run blocking or pass protection or Miami will be hard-pressed to score more than one touchdown per game.
