Is Bundesliga average goal production a season in decline ?
This season in the Bundesliga the average goal production per game is 2.76 , last season 2.83, 2014-2015 2.75 2013-2014 3.16
Rory Smith advised that there has been a “subtle shift” in goal production in the Bundesliga when he simply wanted to discuss a new football metric
“Much of its work has focused on a metric it has developed called “packing,” which counts the number of players taken out of the game — outplayed, as Impect calls it — by a particular move, be it a dribble or a pass.”
Mr Smith et al have failed to acknowledge that expectation of a goal is dependent on the current score ( game state ) in terms of the effect on accuracy as time decays.
In general the opening goal by the away team in the Bundesliga in the 0-20 minutes time band will result in acceleration of goal production and a high early away goal production in a season will raise the average goal production for the season.
2015/2016 2014/2015 2013/2014
Games 52 43 56
Over 2.5 75% 74% 80%
Over 3.5 56% 47% 61%
In the table above I have added all the games in the Bundesliga in the last 3 completed seasons where the away teams opened the scoring in the 0-20 minutes time band to define the % that ended over 2.5 goals and over 3.5 goals.
This season in Bundesliga in games where the away team opened the scoring in the 0-20 minutes time band ;
2-3 0-2 2-2 0-1 1-1 0-2 0-3 1-2 1-1 0-2 0-1 0-3 1-1 2-1 1-2 1-2 1-1 4-1 3-1 1-4 1-1 2-5 1-3 0-3 2-2 1-2 1-1 2-1 3-3 1-5 1-3 3-1 0-2 <> 33 games with an average goal production of 3.24
Summary
In Bundesliga this season compared to previous seasons we are seeing a lower early away goal game production which as a result has effected the average goal production for the season.
after I wrote that blog response < we had a load of early goal games that produced a load of goals in Bundesliga
