Reddit:Last 5 yrs of Wk 3 Preseas. vs. Reg Seas. Performance

PaulBlakeTSU : 8/23/2016 10:54 am
I thought some might find this interesting. People often make claims about what the third game of the pre-season reveals, so a user on Reddit (/u/440k) went back to look at the last five years of Week 3 performances and compared them with the regular season results.

Quote:

Here is what I found:
I took a look at the most recent 5 seasons in the NFL, and their accompanying preseasons. I decided I would compare the winners of Preseason Week 3 games to their win totals for the season.

2015

In 2015, the teams who won their preseason Week 3 game were the following: Bengals, Bills, Broncos, Browns, Cardinals, Chiefs, Colts, Dolphins, Eagles, Jets, Lions, Patriots, Redskins Seahawks, Texans Vikings

The combined wins of these 16 teams was 148.

The combined wins of the other 16 teams was 108.

2014

The combined wins of the 16 2014 winning teams was 132.

The combined wins of the other 16 teams was 123.

2013

The combined wins of the 16 2013 winning teams was 147.

The combined wins of the other 16 teams was 108.

2012

The combined wins of the 16 2012 winning teams was 134.

The combined wins of the other 16 teams was 121.

2011

The combined wins of the 16 2011 winning teams was 142.

The combined wins of the other 16 teams was 114.

Summary

You have probably been able to see this if you've followed along this far, but according to this data, there is indeed a correlation between Preseason Week 3 results and Regular Season results. In EVERY one of the past 5 seasons, the Preseason Week 3 winners netted more victories in their schedule during the regular season.

In 2015, Preseason Week 3 winners netted 37% more wins during the regular season

In 2014, they netted 7.3% more.

In 2013, 36.1%.

2012, 10.7%.

2011, 24.6%.

tl;dr

In the most recent 5 NFL seasons/preseasons, NFL Teams who win their Preseason Week 3 game net 23% more wins in the regular season, equating to almost 2 more wins on average per team. Additionally, playoff teams are made up no less than 50% each year of Preseason Week 3 winners, the average being 63.33%.


I thought the results were interesting and while it isn't a great tool to forecast individual team success, it does show a correlation across the league.

If interested, I recommend reading through the comments as other statistics-minded people chime in and flesh out the conversation further.

Pretty interesting. Thanks for posting.
Agreed

thanks for posting. Not conclusive but certainly interesting to see.
food for thought

thanks for posting.

I'd be more interested in seeing how the teams that held a halftime lead in that 3rd game ended up doing the rest of the way. But it's still interesting.

Giants don't usually play like complete dog shit in this coming game but it seems more often than not they don't inspire much confidence in any pre-season, especially under coughlin.

I still think it's impossible to truly quantify these results into anything conclusive but what else are we gonna talk about...
I don't care if we win

But I would prefer not to see our OL and TE's get manhandled by the talent of the NYJ front.
Wow

Thanks for posting.
it's interesting in that it tells two things  
PaulBlakeTSU : 8/23/2016 11:32 am : link
the starters play more than in any other pre-season game, but depth is important because injuries are inevitable.

Given the state of the Giants the last five years, perhaps the only important parts of preseason are how our third-stringers play since they will all be starters by week 4.
People always talk about wins/losses in pre-season.  
Jerz44 : 8/23/2016 11:34 am : link
They don't matter.

What matters are the drives when the first team is out there.

I'd be much more interested to see the same analysis as done above, but counting the score at halftime as the final.

This is the most important point. Week 3, and only Week 3, should be somewhat indicative of a team's fortunes because their starters are going to see significant time. Week 1, the starters barely touch the field. Week 2, they're still knocking off rust and not playing much. Week 3, they're inching closer to the regular season, see actual time, and players who are on the bubble are expending maximum effort to avoid cuts. This is where you start to get a real feel for what a team might look like.
In addition to how long the 1st team plays (as stated above)  
PatersonPlank : 8/23/2016 11:38 am : link
whats also missing is who they played. If a team plays NE and losses, but then plays Tampa Bay in Week 1, I would expect a win.

again, it's not helpful for individual team forecasting, but more in general, which eliminates the "who they played."

Most telling of this is that in the past five years, about two-thirds of playoff teams won their third preseason game and in no season did fewer than half the playoff teams win.
Interesting, first thing I wanted to check was what the past five....  
Britt in VA : 8/23/2016 11:51 am : link
Superbowl Champions did Week 3 of the preseason.

4/5 won in week 3. Only loss was....

2011 New York Giants.

And, even there, looking back, Giants outgained Jets 327-233 in a 17-3 loss. Offense moved the ball for 21 first downs but shot itself in the foot. Jets got one TD after a long kickoff return and another after blocked FG by backup Giant kicker.

The result in that kind of game is easier to dismiss as irrelevant than one in which you get physically dominated and outplayed.
Not a big enough sample IMO. Just coincidence.

Panthers didn't make the list in 2015 but they were in the SB that season.

I don't know if you can just chalk it up to coincidence. Here was one of the comments in the thread that I thought addressed the issue fairly well

I know very nothing about statistics so please correct me if I'm wrong, but it doesn't seem like a small data set to me. It's the records of all 32 teams over 5 years, i.e. a set of 160, or 80 in each group (winners and losers of week 3 preseason games for each season) all composed of 16 games. Or look at is this way - if you have 80 people in 2 groups - A and B - each flip a coin 16 times, that's 1,280 coin flips per group. Surely the chances of Group A getting a heads total 23% higher than group B is extremely small? There might be some confounding variable in there that we're not thinking about but it seems like it being down to pure chance is unlikely.

The biggest factor is the week 3 opponent  
AP in Halfmoon : 8/23/2016 2:18 pm : link
You could play either Jacksonville or the Pats. I think it's interesting but I'm not sure it tells you anything.
To validate statistical significance I believe you would have to do  
jsuds : 8/23/2016 2:19 pm : link
the same comparison for Week 1 winners, Week 2 winners, etc. In the end I think you will simply prove that teams that win are teams that win. Statistics sure would back that up!
