Bills and Steelers historically "lucky" according to FiveThirtyEight article

Recommended Posts

Says the Bills should have an average of 4.7 wins, meaning we have 2.3 wins more than expected based on point differential, which is the same as the Steelers who should have 5.7 wins.

 

Bills are the 9th "luckiest" team after 9 games since 1960, Steelers the 8th based on this metric...

 

That being said the Bills area also ranked 7th in their ELO ratings at 1607 and they project an 11-5 record for us...meaning apparently they feel we will keep being lucky...

Yeah I saw this yesterday. 
 

It seems to me after looking at the information quickly that teams with winning records are in that “lucky” bin and teams with losing records are in that “unlucky” bin. There is very minimal crossover for a losing team winning more than they should and a winning team losing more than they should and in all of those instances it’s pretty close to being 0 difference. 
 

Which I find kind of odd... but it also supports the concept that teams in the NFL are all close in ability/talent and wins are hard to come by in the NFL... or something like that.

Just now, Buffalo_Stampede said:

Ours is actually flawed because we've dominated basically every game we won but let teams back in the game. 

 

I agree with that to some degree and also it is highly skewed by one blowout loss to the Titans.

Projecting 11-5 means 4-3 the rest of the way, which is in line with what our point differential says our record should be. So they are projecting regression.

The concept of Pythagorean Wins would be useful over a very large sample size where game-script permutations are smoothed out but over 9 games it's pretty much useless.  In the Seattle game, for example, the game was 99.9% decided when we went up 41-20 but the Seahawks got a fluke TD and a garbage time TD that made the score look closer but probably did almost nothing to change the win probability at the time they were scored.  So the notion of that win being valuated as less of a win because the margin was 10 instead of 21 (or on the other side the KC loss looking closer than it should) is garbage.

 

EDIT:  It's absolutely true that if you ran a simulation of these 9 games say...1,000 times...our 7-2 record would be in the higher end of the range.  But saying that the AVERAGE result of those simulations would be a 4.7-4.3 record is asinine to anyone who's watched the games.

No doubt luck IS involved, as the difference between a W or L can be a few plays, ref calls (or non-calls), lucky bounce, whatever.

 

But as Buffalo_Stampede wrote, it doesn't apply here. Ridiculous to base "luck" on close scores.

What are these stats based on? Just random numbers thrown together to make random graphs doesnt move the needle for me

 

It's a barely more complex statistic than W/L record itself and the thing it pretends to illustrate (luck) isn't what it illustrates at all.

 

If I wanted to start an analysis of luck I'd look at truly high variance things like fumble recovery percentage, tip drills and wind conditions for FG kicking.

Point differential isn't a very good measure in football. Not enough games to have an adequate sample, gross disparities in strength of schedule (what division in playing the NFC East this year?), etc, etc.

In MLB: 162 games ... it's a damn good indicator of which teams are "better" or "worse" than their records would tell us.

There aware 8 or 9 games played.  One game can skew things a lot and this is low sample size for this kind of analysis.  From watching the games the bills have been the better team in their wins and have dominated at times although the score did not reflect that at the end of the game.  
 

don’t let this worry you.  It’s kind of useless

Is there any stat, too ridiculous, too irrelevant and too insanely picayune for even the most OCD afflicted numerical fetishist to embrace?

 

 

What are the odds that there's a significant and measurable degree of certainty that this bore the tone of a challenge?

I realize some very talented statisticians work at 538.  And I know their game predictions are pretty good.  But if their model says the Bills should have 4.7 wins, their model is wrong. 

 

We didn't get 7 wins off of unearned turnovers or weird bounces.  We outplayed our opponent 7 times this year.  Sometimes I watch a game and feel like the better team lost.  I never had that feeling so far watching the Bills this year.  

 

I think it's interesting 538 attributes the Bills good record to luck rather than to a flaw with their "Pythagorean expectations."  They can't possibly believe their predictive model is perfect, can they?

I agree. Statisticians are an interesting breed. Dealing with them when I’m doing budgets is particularly interesting as they base their view of what I will do across the entire organization (this is in my last life). I consistently outpaced the many but that was never factored in. 
 

I fought it tooth and nail to no avail. That’s just the way they work...and I understand it...but don’t agree with it.

I feel like they are really good at getting the science down for that 90-95% of situations, but can't (due to mathematical models) account for nuance. The Bills have played significantly better than their point differential.

The Bills have an extremely competitive quarterback who is capable of willing the team to victory.  Is that a measurable statistic?

 

The Bills are "lucky" that Josh Allen is their quarterback.

Yup, good thoughts! There's just some things you just can't measure.

The NFL is the worst sport to try and use simple math with since the season is too short and one game can skew numbers so much ala Titans game. In baseball simple numbers mean much more.

‘Nuance’ isn’t included in statistical science. Just saying. 😃
