Devin Singletary YPA vs 8Man box

[GoBills808]

Recently @thebandit27 @Blokestradamus and I had a discussion about Singletary's sparkling 5.1 yards per carry (good for 4th in the league for qualifying RBs). The point of contention was that his average was inflated due to seeing a very low amount of 8man boxes, as illustrated by the NFL's NextGen stats ranking him dead last among RBs facing such defenses at a rate of only 5.3% of his total carries. For reference, Tevin Coleman faced the highest amount of 8man at 40.15% of his rushes. 

 

That is a large discrepancy. Singletary had 151 total attempts last season, and some quick math says he only faced what NextGen refers to as an '8 man box' eight times throughout the season. If true, that could explain his high YPA...he was getting carries vs nickel and taking advantage of some good playcalling from Daboll. Not having anything better to do I pulled up his highlight reel (more on this later) to see what it showed. Examples below-

 

...one of his first carries against the Jets, went for 21 yards. 

 

 another carry against the Jets, this one went for 13.

 

 

 gained 14 yards here

 

more to follow

Good stuff!

[GoBills808]

 this one went for 14

 

 gained 16 yards on this play

 

 he ran for 9 yards here

 

[Sammy Watkins' Rib]

So he is good? Glad my eyes are not betraying me.

[GoBills808]

 gained 7 yards on this play

 

 and finally cause my computer didn't like all these photos- gained 15 yards on the ground

 

...to recap- these are 8 examples of Singletary rushing against an 8 man box. Theoretically (according to NextGen stats) this is all the rushes he had vs such fronts. Except I know that can't be the case since his YPA on these rushes was a sterling 13.25 and according to the aforementioned posters his YPA was inflated by the lack of facing 8 men in the box. 

 

From this we can surmise A- NextGen stats and I have a different definition of 8men in the box (totally possible- as we know the nextgen stats are computed via chip in players helmets/pads so they may not set off close enough to LOS, but cmon...these are definitely 8 man fronts by any stretch, majority run downs as well) as well as B- they might have calculated Singletary's 5.3% vs 8men in the box very low (because these are simply from his highlight reel as referenced above, I don't have the energy to go through every single snap) ie calculated it incorrectly and finally C-unless he lost a TON of yards on a BUNCH of other attempts vs 8man fronts (possible but imo wildly unlikely enough to bring down a 13.25 ypa) then the idea that his overall YPA was inflated due to facing an inordinately small percentage of 8 man fronts is simply incorrect.

Don't need to convert me. The kid is special. Watching his highlight reel and the number of eye popping runs shows me he will have a very bright future.

ESPN did not project DS to be a top-quality RB.  Therefore, there has to be some made-up BS reason why he is not a top-quality RB.

Would he really have to lose a TON of yards?

 

Could we maybe argue D - drawing any kind of conclusion from 8 plays is silly?

 7-8 in the box is standard in the NFL

 

9 in the box is considered stacked

Of course, which is why I specifically chose 8 plays: that's the amount that (according to NextGen stats) he faced an 8 man front all season

ESPECIALLY true against a run heavy team like the Bills

Right. But you’re still trying to draw a conclusion from those 8 plays, just the opposite one. So that’s the same problem.

 

A better way to make any kind of comparison. How many 8 man fronts do RB’s in the NFL face on average? How well do RB’s in the NFL do against 8 man fronts vs not? If all RBs in the NFL, all 10000 carries or whatever, do significantly worse against 8 man boxes and ALSO saw significantly more 8 man boxes than Devin on average, that would support he was likely benefitted from not facing those boxes this year, despite those 8 carries above.

[maryland-bills-fan]

This is true.  They brought in Gore for those "need one yard for a TD or 1st down" plays.  Singletary ran a lot on 1st down, when the DE were wide to contain Allen and the defense had to defend against both pass and run.   The coaches were good. You set up every play to get the max yardage and most of the time it works.  But Singletary didn't have many plays were 3 yards got the first down, which would bring down his averge.

 

Also, the Bills played very conservative when they had a lead and at the end of the season.  If they were ahead in score and in a 3rd and 25,  they would often run a safe running play with Singletary, rather than risk a pick-6 or an incomplete.   So a 15 yard run padded Singletary's yards per carry, but didn't get a first down.  The other team would concede the unsuccessful run for NO first down.  The Bills would be okay with getting 15 more yard of field position before the punt and with taking a minute off the clock.

 

I have never been a fan of "how good his yards per carry" is as a measure of how good he is.  Total yards, for the primary runner is the metric there.  He was #22 in that (#17 if you gave him his average for the 4 games he missed as injured).  That is not good enough if you are going to use your RB as a weapon to beat other teams. It is okay if you just want to look good an flirt with the playoffs.

Yes, these questions are supposedly answered by the Nextgen stats...which was kind of the point of the exercise.

 

If the plays above are the 8 times all year he faced an 8man front, he was actually more effective against it than his average attempt. If they're not, then ESPN's calculating their 8man box very differently than what that defense looks like traditionally. As it stands, I see little evidence suggesting either is incorrect.

[Brianmoorman4jesus]

He’s excellent. No need to punch holes in it. Give him the ball as much as possible 

[Prickly Pete]

He is a superstar in waiting. Just give him the ball.

Yes, if you believe that 8 plays is indicative of anything. Which I don’t.

ESPN says he only faced an 8 man box 8 times. If these are the 8 times then I think it's fair to draw some conclusions from 100% sample size.

Because of social media, opinions are now widely spread, and easily archived and researched, combine that with needing to have a "strong take" to bait clicks,  (just like in politics) no one wants to move on, or admit they were wrong. They can't move on because their previous "take" or opinion is right there, haunting them. They will cling to the merest thread of an argument (or even none at all).

 

I think it's ***** up society at large.

You don’t calculate sample size from its own set lol. You’d make a statistician’s head explode right now.

Sorry, 1000% sample size
