This wall of text could have been summed up with "Meh, if you ignore his big runs, he's just OK."

If only it worked that way.
No. My point was that his 2 big runs provide a bigger skew than the the results would suggest. When nearly 60% of one's runs are for 3 or fewer yards, and therefore the median is a 3 yard carry, than the expected value of a carry is probably closer to the 3.37 YPC 128 carries and not the 1.2+ YPC that those 2 carries skewed it.

Now maybe he's going to be a big home run hitter, but I think at the end of the year, it will be closer to sub 4 YPC than 4.6 YPC.

But the bottom line is they all count. You don't get to not count them to make your argument better.

Unless you feel like taking out every other RB's best runs.

I could so that, but a quick perusal of the top rushers, indicates that of the top 20 besides Fournette, the longest 3 anywhere near 70 yards (Hunt at 69, Blount at 68, and Hyde at 61) with 3 more rushers with a long in the 50s. 8 of those have more 20+ yard carries than Fournette.

In the top 50, 2 other rushers have a long of 75. And 12 have more 20+ yard carries.

So it's clear that his stats are unique with 2 runs 75 or more yards. I just find that be reproducible with so many carries but so few long carries besides those 2 runs.

Yes. But there have been 4777 total rushes thus far or 4647 non-Fournette rushes.

There have been only 4 rushes of 75+ yards, and Fournette has 2 of them (50%), 100 the rate as the rest of the league.

But it drops from a there as he only has 2 of the 18 rushes of 50+ yards (11.1%), 2 of the 25 of rushes of 40+ (8%), 3 of the 47 of the 30+ yards (6.4%), and 3 of the 113 of (2.7%).

Given how rare a 75+ yard rush is, and he has 2 of them, if we would expect that to be indicative of a home run hitter, I would think that he would have more than 1 of his other 128 rushes (2nd most when minus 2 carries and 3rd is 123), to be more than 20 yards.

As it stands, that's a slightly lower percentage than the league average of runs of 20+ yards, he just happens to have 2 extemely long but extemely rare runs.

Taking away the 20+ carries brings the way of the league down to 3.35 YPC from 4.08. Whereas it brings Fournette down to 3.16 from 4.59, almost twice the drop 1.43 YPC compared to 0.73 YPC.

I know this is an LSU message board, so I'm going against have grain, but 2 uniquely long but impressive runs, doesn't somehow negate the fact that he's more likely to get 3 or fewer yards per carry than a YPC of the 130 carries would typically signify.

I bet you're one of those people who like to say things like if we take out the 85 and 72 yard runs we held them to 37 yards rushing.

Fournette has always had big play potential. He broke a 70+ yard run in almost every game in 2015. He was always breaking huge runs in college. His combo of size and speed make him lethal. Team stack the box knowing they need to load up on tacklers to stop him.. Then he breaks though the first level and out runs everyone.

He had 55 yards on 20 carries after that 75 yd run. Teams are going to load up the box because Bortles sucks so bad. They are going to have to find a QB through FA or the draft. Bortles isn't going to get it done.

The fact that his breakout runs go 75 yards and not 25 is a good thing.
It makes the defense account for him in a particular way they don't have to account for other backs.
So they are keyed in on him, loading the box, and the offense doesn't give them much else to worry about, and he STILL averages 3+ yards per carry excluding the times he has been able to overcome that.

And you see all of that and conclude that he's not really a home run hitter?

That's because they get more space than he does. They just can't make as good of a use of that space as he would.

Just happens to? Seriously?

By every game I assume you mean 3 of the 11, and 7 games where the longest run was 32 or fewer yards, and 3 games where he was held to a long of 20 yards?

2015 game logs

And that would make sense if all but 3 of his 130 carries were 18 yards or less.

He actually breaks long runs at a rate slightly lower than the rest of the league, he just happens to have 2 extemely long runs, on back carries.

All I'm arguing is that those are unlikely to be reproducible so when all other data points to > 4 YPC, closer to 3 YPC then I think that's what we should expect. And the few long runs he breaks moving forward will maybe push it to league average around 4 YPC, which isn't a bad rookie season all things considered, maybe even a pretty good.

I guess we'll find out, and maybe I'll be shown incorrect, but when the OP "really easy" is apparently acceptable nonsense, well then maybe something counter is necessary.

I wouldn't have even paid any attention if it was just "Leonard Fournette is having a good rookie season."

Sure, the poster was wrong to say every game. But 3 of 11(and I thin he had two 70+ runs in 1 of those games against 'Cuse maybe?) was probably pretty darn close to leading the nation, if he had four 70+ runs, so is it just another coincidence that he seems to be repeating his big play ability?

I think what's happening here is you're taking that line just a tad too seriously.

How many carries does LF7 have over 10 yards this season?

Where does that compare to the other NFL rushers?

Link it.

TIA

Also, just the fact that he is 12th in YPC while having wayyyyyyyyy more carries than everyone ahead of him and also leading the league with almost 50% 8 man fronts should be plenty enough to easily validate his yards per carry number.

There have been 4777 total rushes of any yardage, with 131 by Fournette. Although this is 1 rush off from his official stats from some reason.

Regardless that is 4646 non-Fournette rushes.

All Rushes

All Fournette Rushes

There were 507 rushes by any player, of 10 or more yards, with Fournette accounting for 13, so 494 non-Fournette rushes of 10 or more yards.

All rushes of 10 or more yards

Fournette Rushes of 10 or more yards

So, if the 4646 non-Fournette carries, 494 are if 10 or more yards, which is 10.6% of all non-Fournette carries.

Of Fournette's 131 carries, 13 are of 19 or more yards, which is 9.9% of Fournette carries.

So the percentages are pretty comparable (1 rush less for Fournette). Just like everything else, if Fournette's 2 long runs were even a more reasonable 50 or 60 yards per the 2 carries, he would be around league average, which I think will be rough not where he ends up for a full season.

Well it validates his 58.5% of carries of 3 or fewer yards, and his 17% of carries with 0 or negative yards.

In fact, Chris Ivory, his teammate, actually has a greater percentage of carries with 8+ in the box, and 62.5% of his carries are for 3 or fewer yards and only 12.5% of his carries are for 0 or negative yards.

So the results are fairly comparable.

And it validates is YPC, as I said.

But all I'm arguing is that his 4.6 YPC, given the data, is skewed significantly. It's normally the expected value, a measure of Central tendency, but in his case, 2 exteme outliers far more than usual.

Statistically, if we were modeling the data for a study, we would usually institute some sort of resampling mechanism (bootstrap, jackknife, etc.), for this very reason. In fact we could do it for all players, to find an expected value and the bias of the expected value of just typical YPC. And Fournette, would like have a greater skew than most players with some minimum number of carries.

That's all I'm saying. I don't have anything against Fournette and think he's done pretty well, but the numbers don't support the OP.

I have read all your posts. Your argument is basically saying that Leonard's numbers aren't as good as they look because he has longer runs than anyone else.......

You have given no positive statement on the fact he has longer runs than everyone else

Those longer runs are great, but are you needing some validation of the obvious or something? I thought that was already covered, but here is your validation from me as well.

I'm just saying that I don't think his 4.6 YPC is as valid of an expected value as we would expect from 130 carries, and I expect it to regress closer to 4 YPC, roughly the league average.

If I'm wrong, then you can point it out, and I think he's good enough to make it more likely that I'm wrong than most players. But I still think the data suggest he's closer to league average, at least for this season on this team.
