I don't think we were watching the same game. Firstly, I am looking at the macro, at the three phases of the game. In this regard there are three stories: the offense played well enough to win, the special teams could have tipped the game to the loss column, and the defense and a clutch play by Tonges were the keys to the win. In combination, the complementary football between the offense & defense overcame horrible play from special teams, that was far beyond just a poor performance from Moody.

From a unit perspective, the special teams gets an F grade with 55% effectiveness (12 of 22 plays). The offense was 82% effective (9 of 11 possessions), and the defense was 90% effective (9 of 10 opponent possessions).

From a position group perspective, there are two groups that stood out in a negative way, the aforementioned special teams, and the offensive line. The starting 5 on the OL didn't play as a group in the preseason, so this was pre-season mode for the OL. The weakest links, Trent Williams and Dominick Puni, should improve as each reverts to the norm. Had games 1 & 2 been reversed, I could imagine Puni might have been held out of the season opener due to his knee injury. The poor line play impacted the whole offense, especially CMC & Purdy. Running blocking was below average and Purdy played with a tiny pocket and high pressure rates all game long.

The defense as a unit and across every metric was excellent. Prior to the final offensive possession, the 49ers gave up 99 passing yards and less than 200 total yards. They gave up only 1 touchdown and 6 of 10 SEA possessions ended with a turnover (2) or a punt after 4 or fewer plays (4). After week 1 play concluded, the 49ers defense was ranked 6th in the NFL based on points allowed, 10th based on yards per play against, and 4th based on total yards allowed. Considering the poor defensive performance in 2024, the defense performance against SEA is the story of the game.

To understand Brock Purdy's performance in week 1, consider 1) he was under pressure on 47.2% of his dropbacks; 2) he attempted passes to only two WRs (Pearsall & Jennings); 3) he lost 2 of 4 of his top targets (Kittle & Jennings) prior to the come-from-behind drive; 4) Purdy targeted Tonges, Farrell, and Robinson for the first time in any game; 5) Purdy finished the games with two injuries that will sideline him for multiple weeks, most likely. With these facts in mind, Purdy was overall effective, efficient, and explosive. His Comp % (74.3%) was 4th best among all starting QBs, his 116 YAC was 7th best, his Y/C of 10.7 and ADoT of 7.65 both rank 14th, as only 20% of his passes targeted a WR. 35% (9/26) of his completions went for 10+ yards and his success rate of 61.1% ranks 2nd in the NFL after week 1. The only metric where Purdy ranks below average among all QB% is Int% (5.7%), which is relatively unimportant due to the small sample size as the majority of QBs threw no interceptions in week 1.

On Special Teams, Skyy Moore was a net positive and Chase Lucas prevented a kickoff return for touchdown. Otherwise it was a league worst performance and Moody's FG miss was just a small fraction of the poor execution. Moody also never figured out how to optimize for new kickoff rules and gave SEA touchbacks on 2 of 4 kickoffs. He is like a golfer with the yips.

Finally, the defense was great as a unit and got big plays from many players. Robert Saleh might be the most valuable addition since 2024. Dee Winters had a great game and new starters all over the defense we're making plays and shutting down SEA in all aspects. The only SEA player of note was Smith-Njigba, and yet his 8.1 yards per target was far from devastating. Welcome back to CMC, Pearsall is rising, Robinson Jr. is a floor raiser, and Tonges won the game with a single outstanding play. This was a game the 49ers would have lost in 2024. This was a win you see over the course of a season from winning teams -- something to build on.
