S&P+ rankings: Overperformance or overcorrection?

[rickyspub 801]

I didn't realize just how simplistic his recruiting model was. Some teams are great at mental evals and some are great at development and others suck. Sometimes you bring in 30 players and others years you bring 20. Then you have the myriad of new hires that change those dynamics and generally cause roster churn. Not to mention coaches coming up from G5 who may be in over their head. A lot of moving pieces to just throw in some percentages and stale recruiting rankings.

Still feel his system overreacts to blow out wins over weak opponents. Woodshedding 3+ sub-P5 teams gives you a big S&P boost against a team that only plays 1 sub-P5 team.

Yeah I just do not understand his model, I think it highly unlikely he set out to make one that made Texas look bad. We do that on our own in the 4th quarter.

I don't get how returning Cosmi, CJ, Duvernay, Keontay Ingram, Sam Ehlinger, Caden Sterns, BJ Foster, Brandon Jones, Malcolm Roach, Jeffrey McCulloch and so forth is the 8th ranked returning group in the Big 12 and the 51st ranked returning group in the nation. If your statistics are producing that result then I question your model.

It seems impossible to get a straight answer to my question.

Yes I get that we are having lots of guys leave for the NFL and graduate. I presume most teams are not starting an entire roster of Freshman and Sophomores though. Surely this does not make us among the worst in the Big 12 as far as returning players. I mean the entire reason we are #4 in the Big 12 by his numbers seems to be inferior returning players to OU, OSU, Baylor, Tech, TCU, West Virginia, and Iowa State. So the whole conference outside of Texas and the Kansas schools are bringing everybody back and therefore Texas should lose five games? Because I don't see how his other two columns would lead him to this conclusion.

I think you’re a little confused here. The category you’re referencing is returning production. It’s basically the percentage of production you return multiplied (based on a weighted formula) by your teams S&P+ from last year. He’s not ranking based on individual players coming back; he’s using a broad set of data that indicates teams get worse when they lose a lot of production. We lost 8 of 11 starters on defense, so we lose a ton of our production from last year. Similar on O, though not quite as drastic. We lose our top receiver and rusher, plus 3/5 of our OL. In general UT will be misleading in this stat because 1) we were under ranked by last year’s system and 2) no school in the country has a greater talent disparity than what was left of the 2015, 2016, and 2017 classes compared to what came in 2018 and 2019. For example,  we likely won’t be hurt by losing guys like wheeler and Locke, even though they made up a large portion of our production (I.e. tackles) from last year. 

One of the biggest the biggest issues with his system is that it weighs the last 2-5 years of the program as one of its 3 metrics. Well, no team in the country will be more misleading based on that metric than Herman with his guys in there compared to the dumpster fire that was Charlie strong for 3 years plus Herman going 7-6 with the mess Charlie left. 

This would also indicate that last year, UT entered the year ranked too low because the Strong years were weighing it down. 

Overall, UT Is an extreme outlier in 2/3 of these categories and there’s good reason to believe we’re underrated based on this metric. It would be nice if Connelly admitted these factors as a reason why UT could be an outlier instead of doubling down on his system being perfect, but I’m sure he gets a lot of flack and it gets old for him.

Seems like he's identified one of the common threads but hasn't figured out how to account for it, that being possession-based offenses like the triple option. There are of course other versions of possession-based offenses like the one Texas rolled out in 2018. Sometimes they're possession-based out of necessity rather than desire or design.

Something about his system is still underrating those teams, enough that he felt obliged to publish this article.

I think the emphasis on YPP is misplaced - S&P+ is based on success rate, not YPP, and thus is not influenced by explosiveness like YPP.  It seems like the outliers are often a product of maxing out their 3rd/4th down conversion rates.  Maybe some styles of offense are more reliable at converting 3rd/4th down.  For instance, Army did both an excellent job of producing a lot of manageable 3rd/4th conversion opportunities (#1 in average 3rd down distance) and were practically impossible to stuff (#1 in stuff rate), so they converted those opportunities like no other team.  However, while Texas' offense was good at producing manageable conversion opportunities (28th in average third down distance), it had a mediocre stuff rate, so I don't know if this applies to them.

[Huckleberry 33068]

Without looking at the specific numbers in detail, being average at stuff rate but having a lot shorter than average conversion distance should lead to an above average conversion rate.

Ha, yeah. He has decided to take on a persona in his writing where he assumes his system is perfect and so any team whose results run counter to his system's expectations must be using some sort of black magic. In reality he understands that his model is evolving and that such situations are actually evidence he needs to continue tinkering, but in his writing he comes across as though he doesn't realize that.

It's understandable from the context of his content creation expectations and driving readership and engagement, but it certainly isn't a plus for engendering faith in his work.

Connelly conflates "math" with his model.  That is empirically wrong, incredibly arrogant and terribly grating.  The outliers show weaknesses in Connelly's model, not problems with mathematics or some arcane powers on the part of certain coaches.  That is exactly what Huck is saying about the way the guy writes.  Even if he later admits the need for adjustments, leading with a statement like this just leaves a bad taste.  And that attitude is a perfect match for his defensive behavior whenever someone questions his model.

[Machinator 32099]

 

[Burt Macklin 19038]

Other thing I’ll say about why Texas is underrated by S&P+ is that this coaching staff on offense and defense both seem to just try to run out the clock when we get a lead. Herman quits running Sam as much and Orlando quits bringing pressure. I think it’s a flaw in the coaching, but there wasn’t a single game we lost last year because of that flaw. This flaw is easily correctable and isn’t representative of our team’s ability if the game were close. 

S&P+ assumes each team is trying to maximie it’s quality of play and doesn’t account for a team choosing to lower its quality of play in order to run out the clock. Like I said, I’d prefer Herman and Orlando quit doing this, but It’s pretty easily changeable and S&P+ downgrades Texas a ton for this. We had a lot of close wins that S&P+ downgraded us for.  

Herman’s teams definitely play up and down to their competition, but I also think that by 2020, our roster will be so talented that we’ll be a lot less likely to lose any of those games, even if the wins are closer than they should be.

We criticize Connelly and his S&P+ because he makes statements implying it is more than it is. He acts defensive when it is publicly noted to have an area of weakness rather than acknowledge failings. Huck doesn’t spout off making excuses for his adjusted stats when they fail to model everything about future contests. It isn’t complicated— the stronger claims one makes, the more strongly he should expect them reviewed.

In his article outlining S&P+ this is what he actually claims:

Quote

In terms of performance, S&P+ tends to hit between 51 and 54 percent against the Vegas spread, a solid range.
It thrives in the realm of win probability — teams given, say, 66 percent chances of winning will win 66 percent of those games over time.

The S&P+ ratings are an overall prediction tool, but honestly, the predictions are just intended to provide affirmation. If you know that the ratings can be used to at least slightly beat Vegas from year to year, then you can trust them in your analysis as well.

I'm sure I'll get negged for this and/or homophobic insults will be hurled at me, but the above seems fairly defensible.

I didn't think he was dismissive at all at the possibility of something real and not imaginary potentially explaining the difference between Herman's actual and 2nd order wins, he just wants a larger sample before coming to any conclusions.  The statement below is hard to square with the caricature presented in this thread that ostensibly claims his system is perfect and anything it can't explain is the product of chance alone:

Quote

Texas’ fans collective response to being projected in the mid-30s in S&P+ was, shall we say, high in volume. And Herman’s presence atop the overachievers list here seems to verify that S&P+ is not well-equipped to handle a Herman team.

Maybe. But I need to see more because really, this four-year overachievement is a two-year overachievement.

Rather it appears to be Texas fans who for some mysterious and wholly inexplicable reason are ready to come to the conclusion that you can bank on Herman markedly outperforming his 2nd order wins on a yearly basis.

How much would you bet on the under for Texas wins next year if we set the O/U at 7.5? Because S&P+ says we are most likely to win only 7. Or do you think we “defy math” when we win? Or that we objectively look like we shouldn’t even be in the 6 or 7 teams outside the polls “also receiving votes” to start next year? Or that our wins, as opposed to the ones he expected, were more characterized by luck last year? Connelly, as your second quotation from him in this post of yours shows, still doesn’t truly acknowledge that his model is missing something. With one breath he will say one modest thing about his model and with the next he will ascribe all its failings to “luck.”

[Fozzz 152]

I don't think it's inconceivable for them to win 7 games but I would be a little disappointed if that were the case.  I think one thing that has really hurt Texas over the past five years has been a lack of continuity on the coaching staff, the offense was totally ruderless under Strong and the defense clearly had difficulty in adapting to the changes required for executing Gilbert's offense.  Next season Texas' players will be playing in both the same offensive and defensive systems for the third season in a row.  That is something that is not easy for a system like S&P+ to capture but will likely pay dividends.

So there is not any confusion, here is what I said:

Quote

Sushi was referring to a comment that Connelly had previously made about Herman having overpeformed his S&P "2nd order wins" record (not the pre-season prediction) in 2015, but Connelly never said his model (S&P) was terrible at assessing Herman's teams.  In 2016 Herman's 2nd order wins was 8.1 and in 2017 it was 7.5, indicating that Herman does not have some hidden ability to consistently outperform his S&P 2nd order wins.  

His pre-season projections have tended to overrate Texas, but given where we finished in S&P last year and what we lost from last year's team, I don't see any problem with his projection for next season.  

Thus, considering the inputs that go into pre-season S&P+ projections, I don't have any problem with his S&P+ projection for 2019.  That is not saying that pre-season S&P+ projections capture all available information that impinges upon Texas' likely win total for 2019.  No projection system could ever do such a thing.

My theory is that there is a bit of a feedback loop there. Their non-garbage opponents have higher rankings because they have good records and they have good records because they play garbage opponents. So the garbage opponents benefit everybody.

Different ways in different sets. The schedule rating on the regular ratings page (not linked in the menu right now) is just the average power rating of their opponents. The schedule rating on the EWP ratings page is the PWP rating the team would need to have in order to expect a .500 record against the schedule they faced.
