MCFC Analytics blogposts Summary #9

In the past week, I found the following posts written using the #MCFCAnalytics data

Some interesting stuff by @PedroAfonso85 building on some previous work to breakdown the importance of ball possession and some discussion about the oft discussed yet hard to quantify, momentum.
@MarkTaylor0 analyzed Blocked shots to find if blocking shots is a talent.
@hpstats visualized points difference “with/without” a player in the starting lineup. Also from the same blog is profiling players based on their shooting
@SportsViz has a video with examples of 3D-visualization of passes using the data from Bolton vs. City game

MCFC Analytics – summary of blog posts # 2

I got good response for the first summary post I did last week. Here is a summary of articles done using MCFC Analytics data in the past week.

@MarkTaylor0 did a great post called “How teams win”. Mark calculated a list of various correlations that lead to wins.

Mark also did another interesting post on Newcastle’s 2011/12 season and the role of luck in their success.

@JimmyCoverdale Did a post enumerating how “Will he score goals in the Premier League? Is a wrong question to ask “ of newcomers to the league.

Jimmy also has a great post discussing the “Effectiveness of Crossing and the correlation with chances created”

@Zahlenwerkstatt did a post ranking goalkeepers in the 2011-12 season based on minutes played, save % and goals conceded.
I have made a couple of follow-ups based on the feedback of “Final 3rd Analysis“ Follow up #1 & Follow up #2

I have a couple of new posts lined up for later this week.

@OptaPro & Gavin Fleig‘s update on the Advanced data & T & Cs

Simon and Gavin released the updated T & Cs this past week allaying apprehensions of some of the bloggers regarding some of the language in the original T & Cs.

They have also announced that the first installment of the advanced data set will be released this week! I am excited.

If you find an article that is using MCFC Analytics data and is not posted here, please let me know. I will add it in the next week’s summary.

Final 3rd analysis – more follow ups

Thanks a lot for all the feedback and discussion regarding the final third analysis. Here are a few follow-ups on the feedback.

Feedback: The correlation between goals scored and passes in the final third is driven by the top 5 goal scoring clubs. If they are removed from the data set, the correlation might be weak.
This was brought up by @WillTGM & @Chumolo

Follow-up:

The correlation is not nearly as strong if the top 5 (goals scored) are removed. However, 5 teams constitute 25% of the sample space. If we cherry pick the top 5, it is not surprising that the correlation becomes much weaker.
I did an experiment choosing 15 clubs randomly from the 20. In several such experiments, the correlation was strong and significant. R² varied between 0.56 and 0.87. The regression was significant. (F-test)
On a similar note, if outliers like Liverpool and Newcastle are excluded, the correlation becomes much stronger.

Feedback: Significance of the regression

@rui_xu brought up a great point about the importance of the significance of the regression and how just R²might not tell the whole story.

Follow-up:
I did the F-test for all the regressions with the following results

For the overall final third completions vs. total goals scored over a season analysis – the regression was significant

For the game level final third completions vs. goals scored by Manchester City analysis, the regression is not very significant. This is most likely due to the small sample size (38 games).

However, when I did the same analysis using data from all the 380 games of last season (760 samples), the correlation was weak (as observed for the 38 games of Man City) and the regression was significant for the larger sample space.

Please keep the feedback coming!

Follow-up analysis: Final third passing and Goals scored per game

This is a follow up to my post regarding the strong correlation between completed in the final third and goals scored.

Question

Is there a correlation between the final third completions & goals scored at the game level?

Analysis

I investigated to see if this correlation exists at the game level using the #MCFCAnalytics data set. I plotted the completions in the final third vs. goals scored for Manchester City in all their 38 games of English Premier League.
Blue = Away ; Orange = Home

Manchester City Goals vs. Pass completions in the final 3rd on a per game basis

Findings:

Linear regression had an R² of 0.04 implying that there is no correlation between passes completed in the final third and goals scored at the game level.
I did the plot for a few other teams and got similar results.
Arsenal – Away and Liverpool – Home. In both cases, Manchester City had very little success completing passes in the final 3^rd. However, they lost 1-0 at the Emirates and won 3-0 at home vs. Liverpool.
Against Liverpool, City had 6 shots on target and 2 off target.
Against Arsenal, City had 0 shots on target and 3 off target.
QPR – Home and QPR – Away. City scored 3 goals each against QPR home and away. However, they had a season high 326 completed passes in the final 3^rd at home vs. just 74 in the away fixture.
Shots vs. QPR Away – 5 on target & 10 off target.
Shots vs. QPR Home – 15 on target and 10 off target.

The City – QPR fixture was that crazy season finale. City fell behind and they threw everyone forward to go for the win and the Premier league title. QPR was a man down from 55^th minute and they defended at the edge of their 18-yard box for most of 2^nd half. This explains the unusually high number of completed passes in the final third.

The above examples underline the rarity of the “goal” event. In any given game, there could be factors like bad shooting, luck, the opponent’s goalkeeper having a great game etc., which could influence the # of goals scored. However, over a season those things seem to even out.

In the next step of analysis I will add a 2^nd variable to the model and analyze.
