Not claiming this will happen here, but just going to mention this: https://en.wikipedia.org/wiki/Great_Flood_of_1862

>The event was capped by a warm intense storm that melted the high snow load. The resulting snow-melt flooded valleys, inundated or swept away towns, mills, dams, flumes, houses, fences, and domestic animals, and ruined fields. It has been described as the worst disaster ever to strike California.

Please read my title. I did not insinuate that height could NEVER have an influence on NFL QB's. But this all stems from Bryce Young being a bit on the short side and every single time a top end QB prospect is 6'0" or a touch under this gets brought up ad nauseam. Yeah of course this data has worked itself out b/c at a certain point height would have some sort of impact but once you hit a certain height it really doesn't matter.

I am aware of how it's calculated. As mentioned, there's a very high correlation between winning and ANYA. Even higher when you look at it by game.

I'm not saying it's the end all be all, there's not one, but it's REALLY good. The point is though, I could use any number of very good advanced metrics and come up with the same results. Height does not impact performance at this level.

I assume this is water-equivalent snowpack, essentially if the square foot of snow melted into water and stayed within that square foot, that would be the number represented in this graph?

The Sierras have an absolute shitload of snow this year, and it's pretty incredible. Looking forward to all that snow melting and being used to recharge our aquifers and reservoirs and growing insane amounts of food.

It's also incredible that over 70 million acre-feet of runoff from rain and snow is expected this water year in California alone. That's almost 6 times the entire Colorado River Basin's flow over the past 20 years (~12 million acre-feet). Of course we can only capture a fraction of it, but it's still enough to bring the state back into a good spot (though aquifers take many years to recharge).

No, it's ADJUSTED Net Yards / Attempt. It takes into account sacks, sack yards, touchdowns, and interceptions. You could include rushing numbers (attempts, yds, TD's, and fumbled) too but it would not alter this. ANYA is a fantastic little metric that highly correlates to winning.

But it's not a "I think it's true" it's "I KNOW it's true". Even this isn't all that meaningful. Averaging more yards per attempt doesn't necessarily matter. There are much better metrics to use that would knock guys like Howell, Minshew, Bridgewater, etc out of this list. Purdy and Darnold were starters last year (on the same team now and only Purdy has a chance at starting but prob not).

I've seen a few posts on this, for some reason, and it seems they were done by those who aren't really into football and aren't aware of meaningful quarterback statistics to actually use for such. Here we are using Adjusted Net Yards / Attempt - a fairly simple but incredibly useful and accurate measure of quarterback play on a per play basis (which is more important than counting stats).

> I was wondering how old the hospital data is?

The data is from OpenStreetMap, crowdsourced by volunteers.

So it might be at most a day old if we're talking about an area with several active volunteers, and a lot older if we're talking about an area that nobody cares for especially.

It's not a government or company dataset where somebody is specifically responsible for updating it at certain intervals that you can rely on.

Because pass attempts is highly correlated with overall yards as shown here: https://www.reddit.com/r/dataisbeautiful/comments/122c5b2/american_football_starting_quarterback_pass/

Since they're so highly correlated, we can ignore them in this chart if desired -- I included them as bubble size because I thought I might get a response like this.

No, it's not news. However, I was expecting to see more outliers like Patrick Mahomes, with a z-score of 1.6. Actually, I just calc'd z-scores for everyone and Tua Tagovailoa has the highest z-score out of starting quarterbacks at 2.88 which is just insane.

While he's not shown on this chart, as I didn't want to tweak data labels for 108 people so they weren't hiding each other, I did do the numbers for everyone who attempted to pass the ball and we can see that Taysom Hill is best in the league at getting the most mileage from his throws and should get more playtime. Also, Sam Darnold as we can be fairly confident his 140 pass attempts for 1143 yards weren't flukes.

Here's the average yards per pass attempt, best in the NFL:

Name Average yards per pass attempt
Taysom Hill 12.63158
Jordan Love 9.285714
Nick Mullens 8.96
Sam Howell 8.894737
Tua Tagovailoa 8.87
Gardner Minshew 8.723684
Teddy Bridgewater 8.64557
Bailey Zappe 8.48913
Sam Darnold 8.164286
Patrick Mahomes 8.101852
Brock Purdy 8.082353
Jalen Hurts 8.045652

On that table, only Tua Tagovailoa, Patrick Mahomes, and Jalen Hurts are starting quarterbacks. The others should possibly get more playtime.

But that's the thing about doing a statistical analysis. You don't really know what you're going to get until you do it. If you never do an analysis on anything that you think is probably true anyway, you could miss stuff.
