The 49ers are 1-0. They controlled their Monday Night Football opener against the Jets for the entire second half and won 32-19, never letting New York get any closer in the final 35 minutes of the game.

Jordan Mason stepped in for Christian McCaffrey, who missed the game with a calf/Achilles injury lingering since early August, and set the pace for the 49ers, rushing for 147 yards on 28 attempts, the most time he has spent with the ball since high school.

Jake Moody made 6 of 6 field goal attempts, including a long one of 53 yards. The 49ers won the battle for possession with a fumble forced by Fred Warner and recovered by Maliek Collins in the first half and an interception deflected by Deommodore Lenoir and caught by Demetrius Flannigan-Fowles in the third quarter.

Brock Purdy finished the game 19 of 29 passes for 321 yards. He threw neither a touchdown nor an interception. Aaron Rodgers threw both passes for the Jets and finished the game 13 of 21 passes for 167 yards.

The Niners scored on eight of their 10 possessions, only having to punt and take a knee on their first drive to end the game.

Here’s what they had to say after the win:

Kyle Shanahan

On Mason’s starting eleven, even though McCaffrey was out:

I never told Jordan he was going to play from the start. I told him he had to be ready a lot, but maybe Bobby or someone else was trying to get him pumped up, but I knew he had to play a lot. I told him he had to play and that he was going to be like he always was: He was going to be a No. 2 running back who played most of the time.

On McCaffrey’s injury:

Same stuff that’s been bothering him all week. Too much going on today. Decision made during the game. Thought it would be wise to leave him out and glad we did.

During the off-season:

I’m with our team every day, so I know there’s a lot of news and stuff about being out and stuff like that, and when are guys coming back? But our guys have been great in practice. They’ve been very focused. When guys don’t practice a lot, I wish we had more. So I wanted to work more with the guys that just got here this week, but being able to do four practices with them, having the extra day, things like that have been great for them.

In defense:

I was really happy watching the defense from the sideline. I mean, they were running and hitting. That’s what stood out the most. They made a couple big plays against us and a couple drives that got them moving. But for the most part, I thought we won most of the downs.

About Purdy:

He seemed very, very good. I mean, there were a lot of plays that he missed. I thought he made some great plays. Towards the end

On Mason’s chance:

I think Jordan looks the same as he always has. Not just Christian, but we lost a whole bunch of running backs. The cool thing for JP is that he came into training camp in such good shape. When a lot of guys are out, one guy has to do a little bit more in practice. Then the next thing you worry about is him being out.

About Moody and Comfort with 50-Yarders:

That’s the difference with Jake. He’s got a big leg and I get a number and know where we can try from. I don’t think it makes a big difference if it’s 50 or 47, I don’t think it makes too much difference to him.

On Mason’s growth:

I think the biggest thing is getting used to Bobby (Turner) coaching him, realizing he’s not always angry — he just stays that way, and learning that and appreciating that. I think Jordan has really pushed himself every year, just by the way he’s trained off the field, by his better conditioning. He’s never been out of shape, but we have a couple guys in our building — like Christian, guys like Fred, Juice, George, guys that are very obsessive about how they train, how they get in shape, how they eat, how they sleep. And I think that’s really rubbed off on JP over the years.

About Aiyuk and Williams:

I think they did a good job. I’m glad they came through it safe and sound.

Brock Purdy

On the offensive:

There are some things that we all, myself included, could probably do a little bit better, just the live speed and having everyone together, being on top of everything – shifts, movements, operations, going against man coverage, finding ways to get free and being on time. There’s just that sense of urgency

About Mason:

Obviously, Christian is the best in the league as a running back and at what he does — that’s not to take away from him — but I think JP did a good job of coming in and filling his void and doing his job to free up other guys and allow us to play our offense.

On the off-season turbulence:

We’ve been through a lot as a team, signing people, bringing people back, Ricky’s situation, Christian – there’s a lot going on. It’s the NFL, you know, crazy stuff can happen. But our culture, our team, what we stand for and how we all come together and find ways to win and support each other, that’s what we do here.

About the field goals:

I’m happy for Moody, but yeah, for us on offense, it’s like, man, we want to score touchdowns.

Fred Warner

About Sörensen:

A great game. I love the way he approaches preparation and the way he leads our group.

To hit the ball out:

That’s something I practice all the time. I try to do everything I can to help our team win games. I know how important it is to take the ball away.

About Mason:

He chose to train here with me and some other linebackers – Flann and Curtis. And you know, we compete here. Even in the offseason, I saw him with a different mindset that he would be ready for his big moment when it came.

On the question of whether Rodgers looked like himself:

Absolutely, he still has that savvy veteran in him, you know, he takes us offsides and throws a touchdown down the field. Classic Aaron. Obviously they still have a few things to fix, but at least they finally got him.

On the defensive mindset:

I think defensively, our job is to go out and win games regardless of what we have offensively. I think if we keep that mindset and have a dominant offense, then we can really overwhelm teams.

Samuel Deebo

On when he found out about McCaffrey:

In fact, we heard the news today and it continued from there.

How he learned:

Kyle came to me and said, “You’re going to make a little contribution to the running game,” and you know me, I’m there for whatever helps the team win.

When asked if he had a moment of appreciation for Aiyuk and Williams:

I’ve had that conversation every day in training. I mean, we’re in the game now, so there’s no point talking about what could have been. They’re here now and we just move on.

When asked whether the 32 points surprised him:

No, I’m never surprised by our offense and, you know, the position our defense puts us in.

Jordan Mason

About the game:

This is just the beginning.

On the question of when he learned to start:

That question is exactly why I’m angry. That’s why I don’t like talking to the media because you say something wrong and then, you know. I don’t know, just skip that question.

On the significance of his TD run:

My family was here, it meant everything to me.

For off-season preparation:

I’ve been doing a lot of different things. More catching, more conditioning. That’s all.

On the question of whether McCaffrey gave him tips on the sidelines:

He did. Just keep going with me.

Nick Bosa

To start:

I’m really proud of how energetic we came into the game and that Fred kind of set the tone with his early play.

On Aiyuk and Williams missing training camp:

Our owners really care about us, and you have to when you have really good players, and we have really good players at every position. When guys aren’t there, we’re behind them. We know they’re going to bust their asses when they come back.
