The Striker Index: an introduction

In addition to the Match Impact Rating, an additional stat called the Striker Index is being developed. While MIR is focused on offensive results as a whole, the Striker Index will focus on goals scored and the shots and minutes it took to produce them.


In addition to the Match Impact Rating you see here from time to time which looks at a player's offensive performance results, allow us to introduce a new statistical formula called the Striker Index which ranks a goal scorer's performance against other players in a league or team.

The Striker Index ranks players from a league or a team against each other in eight equally-weighted categories: total goals, goals per 90 minutes, shots per 90 minutes, shots on goal per 90 minutes, shooting percentage, game-winning goals, road goals, games played (figured as total minutes divided by 90). A rank is assigned to each player in each category and then the average rank of all eight categories is calculated which gives the rank of each player in the Striker Index.

As we are nearing the halfway point of the season for all MLS teams, here is the Striker Index as it stands now (minimum five goals, MLS matches only):

2013 MLS Striker Index
Player Team Average Rank Goals/90 Minutes
Jack McInerney PHI 3.7 0.67
Mike Magee CHI 4.1 0.73
Marco Di Vaio MON 5.6 0.79
Camilo Sanvezzo VAN 6.3 0.80
Claudio Bieler KC 7.4 0.47
Dominic Oduro CLB 7.6 0.49
Blas Perez DAL 8.6 0.53
Kenny Miller VAN 9.1 0.79
Conor Casey PHI 9.1 0.61
Thierry Henry NY 9.2 0.44
Chris Wondolowski SJ 9.3 0.39
Robert Earnshaw TOR 9.3 0.43
Federico Higuain CLB 9.8 0.32
Robbie Keane LAG 9.9 0.64
Will Johnson POR 9.9 0.35
Diego Fagundez NE 10.1 0.51
Darlington Nagbe POR 10.8 0.33
Juan Agudelo NE 11.3 0.58
Ryan Johnson POR 12.1 0.41

Jack McInerney at the top is not really a surprise to anyone is it? But what separated McInerney from Mike Magee and Di Vaio who are tied with him for the league-lead with 10 goals? Jack Mac also leads MLS in game-winning goals (5) and has scored seven of his 10 goals on the road this season which puts him three goals ahead of anybody else's road goal total.

Even if Magee is only second in the Striker Index, Galaxy fans lamenting poor finishing in recent matches can see that he is leading both the Galaxy and the Fire in goals in 2013. Robbie Keane, for his part, is in the Top 19 above and is mostly so far down the order due to his time spent with the Ireland National Team. Keane is fifth among the Striker Index players in goals per 90 minutes (0.64) and third in shooting percentage (26.3).

Several teams did not have a representative in the Striker Index while the Portland Timbers, which lead MLS in goals scored, boast a trio of goal scorers. Just off the list for Portland were Rodney Wallace and Diego Valeri who both have four goals on the campaign.

Looking back to 2012, Wondo's lead in the Striker Index at the end of the season over Kenny Cooper was 1.8 to 3.4. Keane finished third with a 4.8 average in the eight categories of the Striker Index.
