Some WhoScored Crew Analysis

Who Scored is one of the only places (if not the only place) that rates each MLS player each game, all season. They also rate another 10+ leagues that span the globe. Just like anything, it isn't perfect but it does give us a general indication of which players are doing well.

I like tracking such things but often times things like a game by game player rating might get over looked because of another story or just not enough time to put together a coherent thought.

What I've done here is take each player's rating when they started and broken each out into one of three categories.

This is any score above the best median player score on the year (Chad Marshall's 7.36, which was good enough for WhoScored's 2013 Best XI). The % in the chart is out of total number of player starts. I should indicate it on the chart but it's the holidays. Alright, I'll get to it soon.

This is the middle column. It's the percentage of times the player performed above the median starter's rating for all Crew players.

I work in the retail industry where a metric called NPS (Net Promoter Score) is very important. What it does is throw out the average scores and only look at the best and worst. I like looking at NPS with player ratings because you can really waste a lot of time dissecting average performances (or players). For this quick exersize I decided a 'top' Crew performance was 7.17 and above. A poor performance was 6.49 and below.

For all three above, the higher the better. I've sorted by the aggregate of all three.

One of the reasons this doesn't get a more serious look is because I don't have enough time to fairly compare it to the rest of the league. This just tells me which Crew players performed the best vs. other Crew players.

That said, I'm familiar with their ratings to say that a MLS level player should have a 'Net Promoter' above 50% if they have over five starts (George, Finlay, Finley, Warzycha, Schoenfeld are light).
