QB Brock Purdy Thread

Brocks throws a handful of extremely dangerous passes per game. We have to live with that unless you just want safe check downs all game

Yeah, Brock sucks, let's hope Mac is Brady 2.0

What if a defender just happens to make an incredible play on a ball that he intercepts? Is that the QB's fault too, or should the defender be given some props for his effort?

In the context of the Ravens game, I don't think there could be a more favorable description of Brock's 3rd interception than it simply bounces off Kittle up into the air for an interception.



What do you think?

It's hard for me to see what happened on the ball to Kittle in that clip, but I, as I said, I wasn't talking specifically about any particular interception that Brock may have thrown, and he's thrown a few doozies, but just asking in general. The other poster seemed to suggest that any interception, no matter what the circumstance, should be laid at the feet of the QB, and I was just asking for clarification. Brock had several picks in that Raven's game, which was clearly one of his worst, but was the ball that was tipped in the air and caught by another defender, really an example of bad QB play on his part, or just bad luck, or good defense?

As I mentioned in another post, Brock is clearly a bit of a gunslinger, which I think is a valuable part of his game. But, at the same time, I think it's good that Jones has been showing that the offense can work by taking what's there. Perhaps while Brock has been watching the film from Jones' three starts, he'll be reminded that, yeah, I don't always have to go for the kill shot, I can go for the first down, keep the drive going, and keep the other team's offense off the field. win, win, win, as far as I'm concerned.

I think Brock's play through his first two years has earned him a bit of latitude, but it seems to be typical of this fan base that if a back-up comes in and has some success, then all of the sudden everyone is clamoring for them to start because it's right in front of their faces and easy to process. Much easier than having to look ALL the way back to 2023 to remember how well Brock was playing,

The point is Mr. Purdy is turning into a turnover machine. It was evident last year, and in the Seattle game this year. I have no idea why peeps feel the need to provide a 'nuanced' analysis explaining the reason behind each and every int. You either can protect the ball more often than not or you can't. Good qbs limit their turnovers. Not counting lost fumbles Purdy is at a 2td to 1int ratio which is reminiscent of your avg Qb. You can only get away with this s**t if you're Brett Favre-like with a bionic arm.

Lets hope he can turn this s**t around, starting with his health.

Well it earned him a contract worth up to a quarter billion dollars, lol. There's always going to be groups of people clamoring for the backup, especially when they play well, but it seems wholly ridiculous to think the team is anywhere near a real QB controversy. It's mainly just noise from hot take types and kneejerk fans at this point. I don't think it's an actually popular sentiment.

You don't understand why a more nuanced analysis is needed? Really?

Go look up the pressure Seattle was generating in that game. Looking at his two interceptions to understand the difference between the two is pretty important when people are trying to claim he's making poor decisions on the regular.

If you want to make a blanket statement that he's turned the ball over too much - ok the numbers are the numbers.

However then don't turn around and try to make other narratives from those like Brock plays too much hero ball or makes poor decisions too frequently and site the turnover numbers as proof.

Which has been what people have tried to do in this thread and when I've asked then to show examples of those being recurring, there's crickets.

Well, again, there are turnovers and there are turnovers. I guess it's easier to just blame the QB for all of them since the ball starts out in his hands, but I don't think that's a very accurate take. While I wouldn't feel compelled to go back and break down the reasons for every interception that Brock's ever thrown, I do think it's necessary to acknowledge that sometimes, things lead to interceptions that are beyond the QB's control and occasionally every QB will go through a streak where it all breaks the wrong way or, as in the Jags game, there may be an underlying injury issue that plays a part in the outcome.

Brock has acknowledged on several occasions, the need for him to protect the ball, but he has also shown the confidence, and willingness, to make the tough throw, which is why he was at, or near, the top of the league in yards per completion his first two years. Sometimes, you have to live with the bad to get the good. But that's also why I think Jones' turn at the position has been a good reminder of the lesson that sometimes less can be more. We'll see if Brock takes it to heart when he's finally healthy enough to play again. Go Niners!

Saw this chart just now and thought it was kind of interesting. Question becomes why is Purdy not going to his first read as often?


Some others related to the two guys playing QB for us


This one I found pretty interesting because I know there was a narrative that Purdy struggles vs Man cuz of his arm and by some of the same people who keep saying how Mac's arm is clearly better


I know some don't care about these charts but they're a pretty good way to add some extra info to these evaluations and why people claiming Purdy is going to lose his job don't have much behind that take at least at this point.

We're lucky to have these two guys right now. I wasn't a fan of Mac being brought in and didn't believe in him, glad to be wrong on that one.

I don't recall ever saying he likes to play hero ball. Poor decisions yes, I'm implying that. Maybe it could be also be attributed to his limited arm strength (ala Nick Mullens or Shaun Hill). So everything has to be almost perfect for Brock. He needs to be completely healthy when out there. His receivers run their routes correctly and get some separation. Run game is making dents. Oline gives him enough time to make a smart decision. Bonus - he's not playing a defense that is having an all-time great performance. Then all will be good. And that goes with pretty much all Qbs and hardly ever happens. Okay I think I understand. Maybe, interceptions, as back-breaking as they can be, are overrated to an extent.

FTR, I view the current QB situation as a good problem to have. I hope Mac can stay healthy and still wheel and deal like he has been doing. And I hope Brock heals up soon to 100% and gets out there and clearly shows us all why he's worth 265M regardless of not having the requisite supporting cast and all odds against him.

Btw, who the hell is Adrian Martinez?

And that's why I take issue with people who make these conclusions.

Have there been poor decisions? Yes of course, every QB makes those. Especially when they don't have their best out there and feel the need to press. But his decision making has not been a HUGE problem. Not anything like Jimmy G when he was trying to do too much.

And no I don't believe everything has to be perfect for Brock. It hasn't been perfect for Brock ever. Even in 2023 when he was in MVP discussions and CMC was having the monster year that he had we had issues, specifically on the OL with some injuries mixed in there.

But we have to remember what our offense calls for and Brock's strengths as a QB - timing, anticipation. When these things are off, it looks ugly. Small faults or missteps by the guys around him and what could've been a huge play now looks like Purdy doing something stupid.

Like the first pick vs Seattle. That's a huge gain to Jennings 95% of the time. The right read but one issue on that one. CMC falls down chipping the defender coming in on the blitz so the linebacker who would've been on him is able to hang back and makes a great play to jump up and get the pick. If CMC doesn't fall down the defender has to account for him in the play and the throw is open for a huge gain.

I think it's important to note which decisions are actually poor - like the 2nd pick he threw in that game vs ones that are good decisions but the execution wasn't what was intended whether due to poor throws, fluky game situations like guys falling, drops/batted balls or just great plays by defenders.

I think for the first time since Montana and Young, we have two quarterbacks on the roster that we can win with. Both have a lot of strenghts and opportunities for growth but within the 49er system they do well. In this league having two very good QB's is a blessing.

Two things I worry about Brock coming back. One I hope he avoids the mentality that he has to prove himself and rushes and as a results he increases in making mistakes by taking unnecessary risks. Brock needs to play within the system and if he does that, he'll be fine I believe.

Second, the 49ers MUST address their OL. The OL sucks. Give both Mac and Brock more protection and then watch out. It would also mean a double threat with our running backs be able to really be a threat. Imagine if our OL was even just a little bit better how much of a threat the offense would be.

I question how this is calculated. Brock is very good using his eyes to manipulate zone defenders (Mac is too). Where his eyes are looking as he's dropping back does not always equate to that route being his first read.

I assume they're pulling the data either from PFF or Next Gen Stats. Of course who at those respective sites has deciding when the QB goes to the first read is another story.

Yup looks like PFF based data source.

Yea, how would they know what their first read was or even what they were reading? It's not always obvious.
