Rex and YPPT, what you should be concerned with

[Mikie2times]

YPPT is how many yards it takes to generate one point. It can be measured for both offense and defense. It's not common at all to see consistency year over year in this metric, especially on defense. It is common for this metric to have a regression to the mean if teams start to deviate too much. If you want to make a few wagers next year, take a look at what teams are falling outside of standard deviation in YPPT and I would bet you more often than not you're looking at a team with value. They're generating yards or stopping yards at a rate that isn't reflective of the league average PPG based on the rate of yards allowed. The stat itself is influenced by many factors. Offense, turnovers, ST's, defensive 3rd down %/RZ/big plays. A lot of noise goes into it, but most years, the big players come postseason time are top 5 in either offense, defense, or both. Rex seems talk about leading the lead in defense a lot. When he says that, he's always referring to yards and not points. After running this data, I can see why.

 

2015 #19 Yards, #15 YPPT

2014 #6 Yards, #30 YPPT

2013 #11 Yards, #23 YPPT

2012 #8 Yards, #25 YPPT

2011 #5 Yards, #29 YPPT

2010 #3 Yards, #14 YPPT

2009 #1 Yards, #8 YPPT

 

Trust me when I say the consistency of this profile can't be explained by offensive futility. Buffalo Ranked #4 in Yards and #7 in YPPT in defense in 2014. You don't see this type of consistency on defense each year and if you do, it's usually only a result of an elite defense, 2-3 years max, and the YPPT is too the positive against yards, not too the negative. Further, you don't see championship teams with poor YPPT efficiency. It's a heck of a lot easier to generate points with the yards you have and be more efficient, than have to generate more yards to make up for inefficiency.

 

This is a death blow to my confidence level. Playoff teams don't finish poorly in this area, the consistency is overwhelming for the stat itself. If games were only one with yards and not points we would have one of the best. As is, this appears to be the anti bend but don't break. More like never bend, ever, and either win on that series or break in half.

i appreciate the information and i value metrics used to show success or failure. but beyond the metric stats, beyond the information passed to generate the fact that our defense regressed in 2015 and is likely for a downward trending swing - it is clear that rex ryan did not do us any favors.

 

there isn't much to look forward to in thinking about 2016 because the reality is we still remember 2015. while offense is fun and gets all the glamour we were reminded that defense rules the day in the super bowl. hopefully, this sent the necessary chills down everyone's back to wake us up. our defense needs stout improvement if we are going to be a serious playoff team. our offense can win us ball games.

Thanks, I actually was looking for as much half full data as I could. Sort of trying to look at this thru the lens of Rex Ryan minus the 2015 season. Reality is, I have a hard time coming to a happy place even though I still hold out hope that things are possible. Those thoughts are based on nothing to do with 2015. In general terms, my hypothesis, Rex has failed to adapt to the league wide aerial assault. His roots were based on learning defenses and defensive styles from a different era. While I think going run and being contrarian on offense is solid (as more and more defenses shift to pass defenders), staying large and over sized at LB, not building on 3rd down defenders at LB, not having a more modern 3-4 edge focused defense (Denver) vs being multiple. I just don't know if he understand how to adapt his system to today's game. Factor that in with an uncanny consistency to allow offenses to convert what yards they do generate into points. Just little to work with even subtracting out the 2015 Bills.

good thing we brought in his brother Rob. Just in time.

If you give up the least yards, it only stands to reason that your YPPT would be hardest to keep low. If you gave up a s**t ton of yards and a lot of points as well, your YPPT would be average. Why don't you just tell us where his Jets defenses ranked in terms of total points allowed. This is a relatively meaningless statistic.

Interesting metric.

 

I think Rex is expected to get the defense up to snuff this season, and he knows it.

 

I also think he could be sacked if he doesn't and the season is another disappointment.

 

The story of this season is going to be the development of Tyrod, and the development or lack thereof of the D.

Define this in actual terms, correlation is less than .20 which is considered a low to non existent relationship.

Perhaps that's a function of Rex's defense putting a lot of pressure on the CBs? It's good at stuffing plays, but leaves the defense susceptible to giving up big plays. That would make sense.

[YattaOkasan]

Man lost my post. Thanks for your post; I like the data set.

 

To reply for Metz it sounds like he is saying there is an inverse correlation between the yard rank and YPPT. R2 of 0.2 seems low but sounds reasonable. I would set the alpha on the slope of the line to be 0.05 or 0.1 to see if there is statistical significance. Should be easy enough to run/show.

 

I am also interested in the relationship between offensive performance and YPPT. I don't think its a coincidence that the only year Rex had a higher yards rank then YPPT rank was the year he had his best offense.

 

I do think you draw too many conclusions on this data set alone (Rex not building 3rd down LB's; edge versus multiple) unless you have lots of data you are not showing.

 

Either way thanks again for posting and I would love to know the source because I'm bored and need to practice some stats. Maybe it would be a fun multivariate project.

I don't mean to be obtuse, but in one sentence or less, what is it that I should be concerned with?

[LeGOATski]

Seems to coincide with the quality of his OC/talent on offense.

 

He had Schottenheimer, I think, in 09-10 with a great running game (Tomlinson) and those teams got to the AFCC. In 2015, he's back up to #15 YPPT with a good OC. And hopefully the entire defense is #allin this year

I'm guessing because a good offense generally gives the defense better field position.

 

I have no idea what the actual numbers are, though.

You see why the statistic has so much variance year to year on defense. Offense does play a role and so does special teams. Turnovers play a role. After that all your defensive factors and the strategy of the defense itself. Notice Denver not cracking the top 10 in 2015? Why is that? Why does the list have so many repeats but in repeating, doing so with different profiles as far as yardage? How do teams with bad defenses rank high? What is the path toward success, that's a lot of playoff teams, can you even make the playoffs being very inefficient in this area? It's hard to crack the top 10. The formula on how they did it/do it is all completely different. Consistency is rare and poor performance is nearly certain if this rating is poor. The margins aren't big enough to lose this measure of efficiency and still win. You asked for the PPG profile and here it is. Pretty much reflective of the data in my opinion. Rex discusses being #1 always in terms of yards, never points. I would love for a reporter to ask him why that is and back it up with data that I'm discussing and see what his response is. Not trying to put him on blast, I just want to know his opinion.

That's the million dollar question. He has had poor offense which can contribute poorly to this metric. Bad special teams can also contribute poorly. Then you have his overall strategy, which is highly aggressive. To your point, that would seem to be a logical conclusion to form. Sort of the anti Walt Corey. All I know is that the trend is concerning. It is very hard to win showing negative performance in this area. I would venture to say no team has qualified for the playoffs with a net YPPT rating 1 standard deviation below average in probably a long time. So to see such consistency which is rare and for it to be so low, it is concerning for those that hope he can break thru. Looking at PPG, what is he even breaking thru too?

being ranked low means teams had to gain fewer yards to score points? isn't that mostly a result of field position?

I wasn't basing that opinion at all on the data I presented. I'm cautious to draw many hard conclusion on the data I presented. Other than 1. His consistency in this area is concerning 2. Something is likely creating consistency in this area or many somethings and it's possible those something still exist. 3. Poor performance in this area is a death blow.

Getting back up to the top half of the league last year is good though, right?

Field position plays a role as do many other factors. I have yet to be able to pin down one piece of data with a very strong relationship. Sometimes you see good YPPT with high turnovers, sometimes you see it helped having a great offense, sometimes you see it with great special teams, combinations of all the above, but generally unique to each team and not prone to heavy consistency.
