It’s amazing how this game was a turning point for the 49ers franchise. NFL history changed forever this day.

Our lives as 49er fans changed this day

Came back to see the beginning of Brock. Let's go Niners!!

"He will load up and throw an interception" got me good 🤣🤣🤣13:26

The fact that the 3rd string qb for niners played that well is amazing

As a panther fan, I'm glad to see CMC thrive with a team who won't squander his talent 👏

That throw Purdy made at 5:55 makes me believe we'll be good the rest of the season with him.

It’s amazing how much Brock Purdy impacted this team and has improved! Love this player since this game.

3 sacks by Bosa is insane 🔥🔥

Purdy stepped in and delivered! He showed poise, composure, and threaded the needle in many of his completions. He also showed his mobility outside the pocket and was able to convert on many 3rd downs. He’s our guy going forward and he fits right into our scheme. Keep a strong running game combined with the best defense and I like where we are at. Short week off a big win so hopefully we can take another W soon! Go 49ers!

I'll give Purdy credit, dude made some crazy tight throws for a backup

I only have one thing to say! That was a Purdy good win 🔥🏈

Today 49ers answered the question of what happens if you take the best defense in the NFL and add Arik Armstead back into the mix. My goodness.

1 year later. Thank you Van Ginkel ❤️💛 Purdy has been exactly what SF needed

That was the most amazing lost of 5 I’ve ever seen. Deebo Samuel is a freakin monster. He’s just so good. You can’t hate him. You really can’t 😅

The *_"And he’ll load up and… throw an interception"_* was hilarious.

Purdy looked purdy good! And nobody can stop this defense from slaughtering teams

That throw to Kittle was insane. The dolphins really had me in the first half, well the first 10 seconds actually.

The 49ers defense is insane🤯

Great job by Purdy, especially since Miami was blitzing nearly every play to try and shake him up and force errors but he handled it well. Great game as a team.

Love rewaching this, this is where it started

This kid could be good. Very surprised he fell to last in the draft. Quick release, today’s typical NFL size, elastic arm, has more guts than most starters as of now and is pretty accurate. He throws off platform and from different arm angles, very quick release, great upper and lower body disassociation and finished with his weight back with a sudden stop of upper body rotation that leads to balanced squared shoulders. All the things we see in Rodgers, Mahomes and Allen. We will have to see about the elite arm strength though, not enough situations yesterday to really tell yet. I saw this in him 2 years ago at Iowa State and was very impressed. He also has all those weapons and a championship caliber D.

From a Dolphins fan perspective, that was an impressive win 49ers. It was a tough loss for us, but good game. You guys are looking solid and that sucks about Jimmy G's injury. I just hope we can keep everyone healthy and do okay during this tough stretch of the season.

Holy crap that throw to kittle from purdy was BEAUTIFUL

The legend of brock purdy started on this day

Losing Jimmy sucks, but PURDy stepping up much respect! What I really liked is when PURDy had to roll left and threw pass. Staying in pocket and throwing it down the middle, rolling out right keeping play alive and still scanning down field to hit Debo for a first down. Then the qb sneak. We got a real dog in this game!

As a Iowa State fan, I’ve been waiting for this day. Everyone slept on him. #262 to some people, #1 to me.

49ers defense is LEGIT! What a game by Bosa and everyone else! #DPOY

Its crazy how much we relied so much on field goal kicks back then. Nowadays its touchdown after touchdown for the 9ers. Jimmy g going out was the best thing to happen to this team.

Purdy in the super bowl a year later 🔥🔥🔥🔥

Man the addition of Caff has really made the 9r's offense look rejuvenated and exciting.

Dre Greenlaw was MVP. He is incredible every week.

Purdy put on a stellar performance! 👏🏽👏🏽👏🏽

From purdy first start as Mr irrelevant to a exactly a year later hes the league leading odds at winning mvp INCREDIBLE STORY FOR BROCK PURDY 🐐

The fact that everyone is talking about Micah Parsons as DPOY and no one is even mentioning Bosa is ridiculous. Hopefully that changes after today.

One thing people might forget is the two brilliant challenges by Shanahan

Purdy is not only a great passer, he can run and move also ! Great job Niners !

The game that birthed the legend of Brock Purdy.

I’m back after Purdy got his pro bowl start. To come this far is simply amazing

Niners are looking SOOOOO good right now. Sucks that JG is out for the season, I hope he heals up soon, but Purdy... Man what a debut performance.

Really proud of this win. The Dolphins are a legit team and the Niners went out and proved they're a force to be considered heading into the playoffs.

For the love he showed the Charlotte metro, my home, I am a McCaffrey fan for life. He played through injuries and on a team that was wanting, yet he gave it 100 percent daily. Get 'em young, enjoy this ride, you deserve it.

Brock's origin story

“He’ll load up and .. throw an interception “ 💀💀💀. Delivery had me weak

What a statement win! Man these Niners played HARD! Everyone stepped up and Purdy came out playing just like he did in Preseason. Get ready to see a spike in #13 Jersey sales!

Anyone come back to this to see how far purdy has taken this team? Now they're im the superbowl!

coming from a chiefs fans, 49ers gotta be the most creative team in the league. i say this every week but I just luv watching their style of football

Purdy was awesome off the bench.A very mobile QB. Some really sharp passes on the run. I'm very impressed by this kid!

This 49ers defense looked shaky at times, but they settled down and showed the NFL once again why this unit remains generational with yet another masterclass to support first-time starting QB Brock Purdy on getting his first career win.

This is the day that everything changed!

Purdy is so good that even the pick he threw was great! It was 4th down. If the ball was swatted the fins gain an extra 20-25 yards.

Happy Anniversary Brock!! Can't believe how far you've come! Now look at you!🥹🙌🏼

3 interceptions and a fumble td against a top 5 offensive. GG’s dolphins

This was a great game for the 49ers they had a good defense and offense.

This will go down as the moment the game that the chosen one appeared. The one to lead us to title#6 and many more. The one to join the ranks of Montana and Young as great 49er qb's. Who would have ever thought? Once jimmy went down I thought our Superbowl dreams were over. While I appreciate Jimmy G and his leadership,professionalism and ability this Purdy kid is just something special and has all the tools to be a great QB for this team and scheme. Kyle like Walsh now has his Montana.

And that 49er fans. A star 🌟 is born..😮

Niners EASILY have the best LB core in the league!!💯

As a dolphins fan I’m glad the game went this way sort of. We haven’t played an actual team with Tua in forever and this will wake us up for the future. Of course the internet went crazy but I wish the 49ers a good season and hope we end strong because we haven’t been this good in forever. Edit: Bro I try to be nice to both teams and people are still talking trash 😭

this day was my birthday and i watched jimmy head to the locker room and thought the season was over, yet prob it was the best birthday gift ever

I honestly thought the game was over for us, but Purdy stepped in and got us the W, that was a Purdy good win, in my eyes!

49ers definitely are the real deal and loved the display shown on both offense and defense from them. They’ll definitely make some serious noise come playoff time. Get well soon Jimmy G.

Man the dolphins talked a lot before this game and thought it would be a breeze after that first play… meet Brock purdy

Glad that I wont get weird stares this week at work for saying that Purdy is a solid talent with great potential to be a real good QB. Great job kid, keep it going!

As a 49ers fan this win was very special, McDaniel, Mostert, Wilson Jr, and Sherfield. Like a nice reunion. Niners defense is elite like the 2000 Ravens defense and hopefully Brock Purdy can pull a 2017 Nick Foles to win a superbowl as a backup qb. But key word “hopefully”…

Coming from a houston fan that was one of the best back up qbs performances I’ve ever seen he looked like a qb 1 out there I just became a prudy fan or is it purdy

If this year has proven anything it’s that QB evaluators in the NFL know absolutely nothing. Mike White, Bailey Zappe, Brock Purdy, Taylor Heinike, Cooper Rush..

JG's injury is surely a scary blow for the niners but what Purdy did was absolutely amazing and competent. Guess the WHOLE team, with their backs against the wall, gave 110% on the field to a well-deserved win. "Go niners" from Sydney Australia.

Jimmy looked so good too. I pray for a speedy recovery and hope you come back to the Niners.

My 49ers been kicking ass lately 💪✊

And so started the legend of Brock Purdy

Probably my favorite game I’ve watched at Levi so far. Love this team!!

Bosa Defensive player of the year! Let's Go Niners. AND PURDY PLAYED GREAT FOR OUR 3RD STRING. LET'S GO NINERS. And that defense is insane🏈🏈

Great win today! The most impressive one so far this season! With Jimmy G out for the game, our back BACk up Qb stepped up today!

It's officially been a year. Now there are MVP talks!

What a game! The tackles in this game were so entertaining and hilarious at times.

The fact a rookie quarterback beat the dolphins just blows my mind and it’s his very first start

This was the hardest hitting game of the year. Damn!

I’m so lucky to have been able to attend this game. This was a huge turning point in 49ers history. Brock Purdy is now an MVP candidate …. Like what?

Good intense game. It's good to see two traditional winning franchises playing winning football again. The 49ers have been good again for some time. And hopefully the Dolphins can consistently remain playoff contenders after this season.

🤣🤣🤣Mosert and Wilson made the defense extra motivated today. We allowed 17 points but I feel like this was one of our best performances on D

Bosa is my MvP. He is a freak of nature!! Ninner Gang showing the league something different. I love this team to death!.❤😤🔥

To Jaelan Phillips, I don't REALLY want to directly say thank you for sacking Jimmy G. But, Thank you.

Pivotal game for the 49ers franchise. Jimmy G's last few snaps as a Niner, and then onto Purdy.

A great day to be a San Franciscan. Both my squads won at home. But the hotly anticipated game between MIA and SF was the best win thus far for the Niners. Our vaulted defense led by Bosa & Warner kept Tua & Hill in check all game. Truly an immovable force.

I’m loving the niners defense!! Even with the backup QB we were able to getter done. Now to focus on the next game! Let’s go faithful niners!!

THIS GAME WAS SO FUN TO WATCH. I LIKE THIS PURDY GUY. I LOVE OUR DEFENSE. GO NINERS ! ❤💛🖤

Tyreek Hill 14 targets 9 receptions 146 receiving yards 1 receiving touchdown 20.6 Fantasy Points!

IMO The 49ers are the closest I've seen to a super team since the rams, top 2 defense phenomenal running back top 3 tight end and top 10 wide receiver, the fact they beat the explosive team in the league convincingly with a back up is absurd.

What an Awesome win by the 49ers! Purdy looked really good! Niners defense rocked! Nuff Said!

13:20 best part. "He'll load up and throw and interception." LOOOOOOOOL

I like that Purdy doesn't play scared. With fins coming after him almost every play he stood tall in the pocket and threw the ball with confidence.

I got the old Niner's anxiety attacks when they were leading by 9 but when Bosa made the fumble - *insert Fallen Denzel meme*. Great game, Dolphins.

Dolphin fan here. Congrats to the Niners. Best team won today. Wish Miami had a good back up QB like Purdy. 👏👍🐬

Jimmy G's last game as a ninner ❤ 💛 😢😢

Jimmy G. going down to injury and the defense continues to make critical plays to preserve the win today

The Niners defense came to play! They carried in Fantasy

The 49ers need to get the run game more involved… as. Lifetime 49er is great to see the last pick QB do so well! Props to the whole team🏆

A legend is born

Per Next Gen Stats, entering Sunday’s game the 49ers had allowed just 71 completions at the intermediate level over the middle of the field since drafting Fred Warner in 2018. That’s 15 fewer than any other team has allowed over that span. The 49ers’ expected completion percentage allowed to that zone in that time (56.5) was the *lowest* in the N.F.L., owing in no small part to Warner’s route recognition, awareness, and efficient footwork, all of which were on display on Sunday. - from NYT Derrik Klassen

Jimmy G out for the year. Purdy gotta show up like this again every week now. I believe in this team to do it.
