Week 2 takeaways: five touchdowns before San Francisco's first punt

San Francisco beat Miami 35-13 at Levi's Stadium on Sunday afternoon in front of a paid attendance of 70,878. The 49ers are 2-0. The game took 2 hours 46 minutes. San Francisco led 35-6 with 3:10 left in the third quarter.

Eight things the official game book establishes about how that happened.

1. San Francisco scored a touchdown on each of its first five possessions#

Drives of 12, 8, 4, 8 and 2 plays, in that order, for 59, 71, 65, 71 and 28 yards. Five touchdowns. The 49ers did not punt until 10:38 of the fourth quarter, by which time the lead was 29 points.

Red zone efficiency reads 5 for 5. Goal to go reads 3 for 3. In Melbourne the same two rows read 2 for 3 and 1 for 2.

2. Purdy threw two incomplete passes#

Twenty of 22 for 287 yards, two touchdowns, no interception, no sack taken, and a passer rating of 149.1. The two throws that did not connect were a short left to Deebo Samuel in the third quarter and a ball thrown away on the right side in the fourth.

The number underneath that is the one worth keeping. San Francisco averaged 13.0 yards per pass play, counting sacks, against 6.0 in Melbourne. The 49ers ran 49 offensive plays to Miami's 56 and outgained them 382 to 284. They faced seven third downs all day and converted five.

3. The pass rush arrived, and it did not come from the edge#

Four sacks for 15 yards after zero in Week 1. Marques Sigle took Malik Willis down for five yards in the third quarter. Keion White took him down for six a few minutes later. Romello Height had one when Miami reached the San Francisco 10, and Warner and Upton Stout split another on the snap before it.

Nick Bosa's line on the Final Defensive Statistics page reads three assists, no sack, no quarterback hit, no tackle for loss, on 40 of the 59 defensive snaps. Through two games he has no sack and one quarterback hit. Osa Odighizuwa, who had four of the eight hits in Melbourne, had one here on 41 of 59.

The team's own shape flipped. Melbourne produced eight quarterback hits and no sacks over 61 snaps. Sunday produced five hits and four sacks over 59.

4. Miami had first and goal twice and scored six points#

The Dolphins' second drive of the game ran 17 plays and 63 yards and reached first and goal at the San Francisco 6 with 11:51 left in the second quarter. De'Von Achane got nothing up the middle. Willis was sacked back to the 10 by Warner and Stout, then sacked again at the 10 by Height. Riley Patterson kicked a 28-yard field goal.

The Dolphins' next drive reached first and goal at the San Francisco 7 with 1:09 left in the half. Four snaps later Patterson kicked a 24-yarder as the clock ran out. Miami finished 0 for 2 in the red zone and 0 for 2 on goal to go, and its only touchdown was a 77-yard throw to Ryan Miller with 2:30 to play and the game gone.

5. Sigle has not come off the field this season#

Fifty-nine of 59 defensive snaps on Sunday, after 61 of 61 in Melbourne. Every defensive snap San Francisco has played. He added 10 special teams snaps, which is 40 percent of the 25 available.

His line: six combined tackles, the sack, a tackle for loss and a quarterback hit. Ji'Ayir Brown led the team with 12 combined, and Dre Greenlaw had eight on 41 of 59.

6. The tight end split held for a second straight week#

George Kittle played 25 of San Francisco's 52 offensive snaps, or 48 percent. Luke Farrell played 28, or 54 percent. That is two games in a row in which the starting tight end has been on the field less than the man behind him, after 30 and 46 out of 65 in Melbourne.

It has cost nothing so far. Kittle caught all four balls thrown at him for 80 yards. He took the first snap of the second half 40 yards to the Miami 25, then caught the 12-yard touchdown three plays later.

7. The running game did not come back from Australia#

Twenty-seven carries for 95 yards, 3.5 a carry. In Melbourne it was 30 for 174 at 5.8. Christian McCaffrey carried 10 times for 23 yards at 2.3, and scored twice from the 1. Purdy led the team in rushing with 30 yards on three carries.

The penalties went the same direction. San Francisco took seven for 78 yards after two for 21 in Week 1, including an 18-yard intentional grounding on Purdy and a roughing the passer on White that turned a Miami third-down incompletion into a first down. The drive that produced the first punt lost 38 yards on three of those flags, two holding calls that wiped out gains of 14 and 8 yards and the grounding, and it still reached the San Francisco 43.

8. Demarcus Robinson did not finish, and the kicker never took a kick#

Robinson was hurt on a 19-yard catch late in the second quarter and was ruled out of the game. He had three catches for 34 yards before that. Mike Evans and James Thompson Jr. were both listed as questionable to return and no return was recorded for either. Romello Height and Jack Jones were listed questionable and both came back. The club gave no body part for any of them in the game book, and the first Week 3 practice report is due Wednesday.

And Eddy Piñeiro, who missed all three practices last week with an illness and for whom the club worked out two kickers on Saturday without signing either, attempted no field goal. He kicked five extra points and six kickoffs, none of which reached the end zone and all six of which Miami returned, for 148 yards at 24.7 a return. The Dolphins' average drive start was their own 31. San Francisco's was its own 35.
