The case for pulling the goalie in soccer and the math behind Ben Olsen's madness

The case for pulling the goalie in soccer and the math behind Ben Olsen's madness

The game is ice hockey. One team is behind a goal as the seconds wind down. Conventional thinking for the head coach of the losing team is to direct the goalie off the ice while a substitute enters the game. This gives the team a six to five player advantage at one end of the ice, but gives the leading team a much higher chance of adding to their lead. Starting in 2013 NHL teams became more aggressive with this strategy, and a paper released earlier this year proposed that teams should get at least three times as aggressive as they are. The math clearly lines up with the strategy.

Lowered Expectations: Week 26

Welcome to Lowered Expectations, week 25 edition! Each week, we go about posting chalkboards and GIFs of the weekend’s best open-play shot attempts which did not quite live up to expectations (and rarely do we update this paragraph). We look at each one and not only evaluate the results, but also the process leading to them.

Expected Narratives: Chara's MVP Chances and Dempsey's Place In History

Ok fine. Nothing Josef Martinez has or will do is within the jurisdiction of analysis. He is perfect in every way. He has created 28 goals from nothing. Where once there were scoreless games Josef declared “let there be goals” and he saw the goals and he saw that they were good. I cannot see how Atlanta fans will take issue with this, so I can’t wait to see the ways in which they will. I’m going to say something nice about Philadelphia now, because I’m jealous that other soccer writing people get their pull quotes immortalized in the awesome brushtip font on Twitter. So here we go:

The Next Level of xG: Expected Possession Goals

Using xPG variants to assess risk-and-reward of the game

We introduced Expected Possession Goals (xPG) in two recent articles. xPG groups and rates the outcome of a possession and began from an idea that every action in the possession connects to create a shot. Here, we’re introducing new xPG variants, extensions to the original xPG definition to assess the risks and rewards inherent in a soccer possession.

xPG rates a group of uninterrupted events - or when an interruption lasts fewer than two seconds - based on where the ball travels. It assumes the purpose of the possession is to move the ball within shooting distance.

The Legend of Josef Martinez and what it takes to get to 27 (and more) goals

The Legend of Josef Martinez and what it takes to get to 27 (and more) goals

Josef Martinez is a man on fire, and, as of writing this, he currently sits on 28 goals in 2018, having just broken the all time scoring record of 27 first set by Roy Lassiter in MLS’ inaugural season and matched by Chris Wondolowski in 2012 and Bradley Wright Phillips in 2014.

But I want to take this opportunity to look at how goal scorers score goals, and compare Wondolowski, Bradley Wright-Phillips and Martinez (we don’t have data on Lassiter, sadly) on their march to 27. Yes, Martinez has broken the record, but this article is going to deal with his stats on the way to 27. For a more complete breakdown of his data and where he lands, I’m sure someone at ASA (let’s say, Harrison) will write you that article at the end of the year.

Expected Narratives: Wazza Saves DC and Josef Martinez is not an Elite Finisher

Ah, Rivalry Week sponsored by Heineken. Who doesn’t want to ride for this twice annual celebration of American soccer’s most storied rivalries and also some ones that MLS just went and made up? Frankly speaking, rivalry week can kiss m-(Editor’s note: I redacted like a whole paragraph here, you’re welcome. Also, Heineken is gross.) - because Atlanta and Orlando are not a real rivalry just because some marketing executive bought a billboar-(Editor’s note: yeah some more here as well) ight- and even if these ARE the most exciting rivalries in the league why not spread those out so you can have a compelling match every couple of weeks? I don’t know folks. I hate rivalry week. It makes the fans extra ultzy, it sort of cheapens the real rivalries, and all these kids will simply not get off of my lawn. Is it mainly because I never spell Heineken right? Mainly. Yes. Whatever.

Ranking the Wingers

/

We’re all here because someone on Twitter started a discussion pertaining to ranking MLS wingers. I’m certain that my rankings won’t satisfactorally answer that question to everybody’s liking, but hopefully it adds something useful to the conversation. First of all, let’s establish some rules.

1)    The definition of a winger for this context is going to be super vague. Essentially a wide player lined up in the midfield according to the team lineup provided at the start of a match. Argue that however you wish. This just seems easiest.

2)    The player has to have played 500 minutes in the position his season. We’re not doing this “well--he’s been a winger in the past” or “he’s been really good when played out on the wing in a few games”. I’m not playing this game. It’s 500 minutes, meet it or beat it.

3)    If you’ve met the criteria above you get a mention in this.

4)    I’m going to provide some data with these thoughts. That will of course come from American Soccer Analysis. I could have broken things down far enough to where we only consider the advanced metrics, but we have to draw the line somewhere so we’re using numbers agnostic of the position played.

5)    Look. This is a rankings list. We’re not going to agree on all of these. It’s perfectly reasonable for you to think that I am in fact, wrong. That is fine. I might be.

Let’s get on with it.

Little Things From Week 25: Tata Tactics, and the two sides of McBean and Steres

Gregg Berhalter and Tata Martino provided another installment of their budding coaching rivalry on Sunday, a rivalry that will grow to the level of Jesse Marsch vs. Patrick Vieira when they inevitably meet in the conference semifinals this year.

Atlanta United and the Columbus Crew have a way of providing open, action-packed tactical chess matches. They did it again at the Benz, a 3-1 Atlanta win. The Five Stripes’ talent quotient was too much for a Crew team that pales in comparison.

Tata approached the game knowing that Berhalter would have Columbus trying to pass out of pressure and play from the back. The Crew are one of the few teams to go to Atlanta and make a concerted effort to control the game. For the most part, they did an effective job of it, taking the ball off the feet of Miguel Almiron and opening chances in the other direction.
