ESPN College Football - Computer Ranking - Top 10

Submitted by Amazinblu on November 29th, 2022 at 10:47 AM

The attached article caught my eye.  The whole idea of ranking - and subjectivity vs objectivity to assess teams while selecting the teams for the CFP - will be an ongoing conversation.   

The link follows (it is not paywalled) and, was published AFTER Saturday's games.

https://www.msn.com/en-us/sports/ncaafb/espn-computer-releases-its-new-top-25-rankings/ar-AA14BK4T?li=BBnbfcL

Here's the latest top 10 from ESPN's computer model:

  1. Georgia
  2. Alabama
  3. Ohio State
  4. Michigan
  5. Tennessee
  6. Texas
  7. Penn State
  8. Utah
  9. Clemson
  10. TCU

Yes, after Michigan's victory in Columbus, the eSECpn computer algorithm still has the Buckeyes ranked in front of the Wolverines.   And, there are only three SEC teams in the Top Five.

As an engineer whose career has been in technology, I'd be very interested in seeing the algorithm that determined these rankings.

My immediate reaction is essentially - incredulous.

When it comes to data and algorithms like this - garbage in, garbage out. Clearly they’re not using the right datapoints as this is incredulous indeed

Algorithm clearly didn't expect (and doesn't going forward) that Michigan would be able to win a game against OSU by breaking the vast majority of its tendencies (explosives).  Down by down, without Corum, we struggled on offense until Q3.  The model just isn't built to handle UM's approach to football.

I fully believe ESPN's power rankings are more or less bullshit, but it looks like the MSN article is using an out-of-date ranking that does not account for Saturday's games. If you go to the ESPN Power Rank page, it shows this list hasn't been updated since Nov 21, 2022 (see bottom left-hand corner): https://www.espn.com/college-football/fpi

A perfect encapsulation of why metrics are often bullshit and why we should never let them take over sports rankings. We've seen the baseball sabermetrics for years tout certain players as having more value than others only to see those players never win a championship or really be a factor at all.

Whatever this algorithm is, it's garbage.

And, in a news conference - Saban noted that Bama's two losses were to teams ranked in the Top 10.

Of course, those were "Top 10" SEC teams when they played them.   Those two teams records are now: Tennessee at 10-2, and LSU at 9-3.   Tennessee is ranked 8th in both the AP and Coaches polls while LSU is ranked 11th (AP) and 13th (Coaches).

Just goes to show the lengths that they’d go to get Bama and OSU in the playoffs and could still happen. If TCU and Usc lose I could easily see GA vs OSU AT 1 and 4 and us vs Bama at 2 and 3. I’m sure the assumption would be that all is right in CFP with a Bama Ga natty.

If your algorithm has OSU over Michigan after Michigan just beat them by 3 possessions in Columbus, your algorithm sucks. Don't come back and say iT's a mOdEl. If it can't even discern that Michigan is better than OSU then it's not worth considering

Points for each game you play against an SEC opponent + points for each ESPN watcher in your fanbase + points for each ABC/ESPN announcer who is an Alum, oh and I guess we'll throw a point in for each victory.

This is straight FUD from ESPN.  Expect ESPN to start pushing some unhinged-from-reality “two SEC teams in playoffs” narrative, and they will start pointing back to this batshit computer ranking.  And way too many people will eat this shit up.

If you don't know what variables are used to obtain such results, it's not really worth a conversation. Bill Connelly says, 'I take this this and this into account' and we stare at it, examine it over time, he tweaks it, and the measure comes to be accepted as fairly accurate or not. If this were about latent potential as possessed by these teams in re: their recruiting, etc., maybe. . . What Harbaugh and co. have made clear is that they can put together teams that are more than the sum of their parts. That's why you play in the first place.

It’s not a ranking of what you’ve done though.

This happens every time FPI or SP+ is brought up for discussion.

Resume-based rankings (AP Poll, CFP Poll, etc.) are fundamentally different than predictive models (FPI, SP+).

This model likely accounts for the fact that nearly all of Michigan’s offense came in about 5 plays and would not expect it to happen again (but that doesn’t mean it couldn’t or wouldn’t).

That said, I would be curious what goes into calculating FPI (SP+ is pretty transparent), but ESPN does keep the lid on it.

I think the flaw in the model is apparent from the results - record isn't taken into account. That is, there is no penalty for losing a game. Most important thing seems to be strength of schedule (1. Bama 2. Tenn 3. Texas 4. OSU 5. UGA). 

Where Baylor is ranked would be informative, because they are 6-6 against a top 15 schedule.

Putting Alabama #2 tells you all you need to know. I would like to see the week to week of this computer ranking. If this is the first week of the ranking, then obviously, the data was skewed to get the result they want. It's ESPN. We know they have no objectivity.

This list is, of course, hot garbage. And it shows that certain people (including some prominent analysts) who have said, "The CFP Committee stinks! You should use an unbiased computer!" are just a dumb -- computers are built by people. They can give you just as bad "unbiased" results (e.g., I am sure the computers absolutely love OSU because of margin of victory).

As someone said, garbage in, garbage out. Stick with the committee with a clear setup (e.g., in new system, all Power 5 conference champs make the playoffs) -- at least then you have someone you can hold accountable.

I have absolutely no idea how any objective tool could look at Alabama and Texas this season and considering them a top-10 teams.  I'm sure their model does that thing all bad models do where it relies on a series of assumptions and they become self-referencing and fulfilling; Alabama beat a top-6 Texas team close so that means Alabama is good and Texas lost a close game to a top-6 Alabama team so that means Texas is good and because of that Alabama's close win over Texas makes them a top 6 team so that's a good loss for Texas to a top-6 Alabama team so Texas deserves credit...and all the way down.  Do the same with Tennessee and Alabama and you see it again.

It's funny to me that ESPN brought on Bill Connelly and his far superior SP+ system and yet still trot out this shitty copy-cat system they created on a lunch break for some inexplicable reason.

Sagarin computer rankings have Ohia Michigan 2-3. Not just ESPN. Shows the flaws in these models when coming off an 22 point Michigan win. Also curious about SOS. Ohia played ND. But Michigan played Illinois.

At some point, people need to actually watch the games. Feng downplays Michigan's win because we won with some 'explosive plays', but doesn't acknowledge that 1 of OSU's 2 touchdowns came on an explosive play and that Michigan's defense held OSU's "elite offense" to only one TD in however many red zone trips they had. Also, our explosive pass plays only happened because OSU sold out to stop the run. If they try to prevent the pass, then we'd just run right over them like we did at the start of the 2nd half.
