Title: The surprising lack of CG upsets in the CFP era
Post by: medinabuckeye1 on December 04, 2018, 07:49:37 AM
When the CFP was formed I really thought that it would result in fascinating debates after CG upsets.  In the five years of the CFP there have not been any major upsets in the CG's.  

2018:
No surprises at all.  

2017:
Based on ranking, UGA>Auburn and tOSU>UW were both upsets but I remember that tOSU was favored and neither was particularly shocking.  

2016:
Based on ranking, PSU>UW was an upset but it was 7vs6 so hardly a shocking one.  

2015:
Based on ranking MSU>Iowa was an upset but it was 5vs4 and nobody was surprised.  

2014:
Technically Wisconsin was favored over Ohio State but it was close and Ohio State was the higher ranked team.  

It is frankly amazing that in all of these CG's the two biggest uspets (at least according to ranking) were #6 UGA over #2 Auburn and #8 tOSU over #4 Wisconsin both in 2017.  Neither of those results were truly surprising.

I was actually thinking that on Saturday, that as much chaos as we typically get in college football, very little seems to occur on championship weekend.  1998 and 2001 are the two examples that come to mind.  Two decades ago.

As an Ohio State fan the one that immediately occurred to me was 2007 when #3 Ohio State didn't have a CG and needed either #1 Mizzou or #2 WVU to lose to either #9 OU or nr Pitt respectively.  As it turned out, BOTH upsets happened such that when the dust settled Ohio State was an obvious selection and the controversy was over #2 between 2-loss league champs:

The OU>Mizzou "upset" wasn't much of an upset.  I pretty much expected that one as Mizzou was mostly a product of their schedule and had already lost to OU earlier in the season but unranked Pitt over #2 WVU was huge.  The Panthers came into the game at 4-7 coming off of back-to-back losses to Rutgers and South Florida.  Moreover, Pitt wasn't even the home team.  Their upset over #2 WVU happened in Morgantown.  

1998 and 2001 were pretty crazy as well.  Tennessee was all but beaten in the SECCG and that would have sent tOSU to the inaugural BCS Title game but then they managed to win.

Part of this is because Team A is often a LOT better than Team B from the other division.

We do see apparent upsets in the Final Four of course judging by seeding, but those are all good teams.

Yeah I was thinking actual CCG, and Pitt over WVU wasn't one.  Like you, I expected Oklahoma to handle Missouri.

Another related item is the old saw about it being tough to beat the same team twice in a season, and yet it more often happens when it is possible.

Of course, when it happens it nearly always is because both teams are pretty good to very good.

oh, don't worry, the upsets are coming
unless the conference office is controlling the Refs AND the underdog coaching staff

Here's the plus side of motivated, big-boy teams with all their goals on the line.  They don't whiff.

I think there is no doubt about this.  When you look at this year's five match-ups, I think it would be safe to bet that on average at least one of the underdogs would win.  None won this year but a year will come in which two or three underdogs win P5 CG's and then it will be utter chaos figuring out the final CFP rankings.

I'm looking forward to it, unless it's the Huskers getting upset

I really will think it's karma when a huge upset happens in the Big 12

It happened in the Big 12 back in the day quite often, and there's no need for it to happen now that they have a round robin schedule

Do you think the Sooners needed the bump they recieved for playing the Horns and beating them in the champ game?

or would they have been voted the 4th slot w/o that game?

I think that would have been an awfully close call between 12-1 B1G Champion tOSU and 11-1 B12 Champion OU.  
Oklahoma still would have obviously had the "better" loss.  They lost by 3 to a top-15 team at a neutral site.  The problem for the Sooners would have been that they would have had definitely less quality wins.  tOSU and OU wins over final CFP top-15 teams (assuming no redemption for OU over Texas in the B12CG):

Looking at that list, OU has a big problem.  Ohio State's signature win is VASTLY superior to anything they can offer and Ohio State has the second (blowout over NU) and third (close over PSU) best wins.  Oklahoma's close win over WVU and their 10 point win over ISU would be clearly inferior to all three of Ohio State's wins over ranked teams.  

In comparing the two teams Ohio State would have an advantage over Oklahoma in both quantity and quality of wins over ranked teams.  Oklahoma would simply have to hope that the committee valued their "good" loss enough to put them ahead of the Buckeyes with their better wins and worse loss.  

That is a really fundamental question of which you think is more important:
We've had that debate here probably 100's of times and I think we are fairly evenly split.  I have to imagine that the 13 member committee would probably also be pretty evenly split and it would probably come down to a 7-6 or maybe 8-5 type decision and I think it could go either way.  

As it happened Oklahoma's 12 point win over #15 Texas gave them the same quantity as Ohio State and rough parity in quality so I think the bad loss was the deciding factor.

To put this in some persepctive I am using the point spreads from the Worldwide Leader and an approximation of how often an underdog of that many points should win from a site called bettingtalk (https://www.bettingtalk.com/win-probability-percentage-point-spread-nfl-nba/) to come up with an approximation of how many of this year's CGs "should" have resulted in upsets:

Ignoring the Pittsburgh longshot:

Again ignoring Pittsburgh's longshot, 11%+18.4%+25%+36.9% = 91.3%.  

That isn't really how statistics work though.  I *THINK* the appropriate formula is to take the inverses and multiply them so, again ignoring Pittsburgh, the chance of the other four P5CG favorites all winning was:
89%*81.6%*75%*63.1% = 34.37%

Fun with numbers:

Ignoring the ACCCG, there were four P5CG in which the underdog had a reasonable (at least 10%) chance of winning.  Four games with two results makes for 16 total possible outcomes (2*2*2*2=16).  Here are all 16 possible outcomes to the B1G, SEC, B12, and PAC CG's this year with their statistical likelihood of occurring based on the aforementioned information:
#NU-tOSUUGA-BamaTX-OUUT-UW% Chance
1tOSUBamaOUUW34.37%
2tOSUBamaOUUT20.10%
3tOSUBamaTXUW11.46%
4tOSUUGAOUUW7.75%
5tOSUBamaTXUT6.70%
6tOSUUGAOUUT4.53%
7NUBamaOUUW4.25%
8tOSUUGATXUW2.58%
9NUBamaOUUT2.48%
10tOSUUGATXUT1.51%
11NUBamaTXUW1.42%
12NUUGAOUUW0.96%
13NUBamaTXUT0.83%
14NUUGAOUUT0.56%
15NUUGATXUW0.32%
16NUUGATXUT0.19%
All four favorites winning is the most likely outcome but it has only about a one-in-three chance of happening.  

In this case the P12CG was effectively irrelevant and the chances of Pittsburgh upsetting Clemson were close to nil but just looking at the other three:
#NU-tOSUUGA-BamaTX-OU% Chance
1tOSUBamaOU54.47%
2tOSUBamaTX18.16%
3tOSUUGAOU12.28%
4NUBamaOU6.73%
5tOSUUGATX4.09%
6NUBamaTX2.24%
7NUUGAOU1.52%
8NUUGATX0.51%
The chances of all three favorites winning were still only barely over 50/50.

I added in what I assume the playoff committee would have done (all assume that Clemson beats Pitt):
#NU-tOSUUGA-BamaTX-OU% Chance1234
1tOSUBamaOU54.47%BamaClemNDOU
2tOSUBamaTX18.16%BamaClemNDtOSU
3tOSUUGAOU12.28%ClemUGANDBama
4NUBamaOU6.73%BamaClemNDOU
5tOSUUGATX4.09%ClemUGANDBama
6NUBamaTX2.24%BamaClemNDUGA
7NUUGAOU1.52%ClemUGANDBama
8NUUGATX0.51%ClemUGANDBama
So, assuming that Clemson beats Pitt, in retrospect I think that the % chances for the other contenders were:

People also assume upsets mean chaos.  Sometimes upsets mean clarity.  If Texas or Northwestern had won this weekend, it would have made things easier.  If both had won it would have made things REALLY easy.

I'm not sure that both NU and TX winning makes it THAT easy.  It depends on the Bama/UGA result.  
In scenario #6 Bama, NU, and TX win.  The top three are obvious Bama, Clemson, Notre Dame.  The fourth would have involved some controversy.  I think Georgia gets it at 11-2 but there would have been a bunch of other two-loss teams in the discussion (tOSU, TX, M, WSU).  
In scenario #8 it is REALLY easy.  Clemson and ND are still undefeated and in.  Georgia is 12-1 and SEC Champs so they are in.  The last spot is obviously 12-1 Bama because everybody else has two losses.

I mean Georgia stayed ahead of OSU even with OSU winning.  I'm 99.9% confident that if what happened, happened, but OSU and Oklahoma lost, Georgia is in.

I agree that is what would happen, I'm just not thinking it would be controversy free.  Michigan would have arguably better losses, Ohio State would have a better win, depending on how close the B12CG was OU might have better losses too.  I agree Georgia would get it but there would be a bunch of 2-loss non-champions to decide between.

The percentages, while obviously due for some regression, will always be higher than the historical percentages for the reason I posted upthread.  It matters.  The percentages include all games - Thursday nighters, season-openers, etc.  It pulls down the numbers, compared to high-quality teams at the end of their seasons with everything on the line.
