a different player
To get here we had to analyze the game of attackers, midfielders and defenders both individually and in the group, taking into account all the time the balance between their contributions more individual and collective, the balance between defense and attack. Goalkeeper arrived all that fades away, fades away as much of the regulation when he bends down and picks up the ball.
is true that like any other player is an individual and a collective contribution from the goalkeeper, but the fact remains that the functional differences between a goalkeeper and another end up being minimal. Yes, sometimes it is the case of one who kicks particularly well and we see it with a sense of whimsy launching a penalty or a foul, and we see that they get the ball played as if they were a libero. It would be interesting to evaluate that as well, but perhaps not relevant.
When considering a straightforward way the value of a goalkeeper should evaluate what it does and where it does. For what, perhaps the two most valuable data are the number of stops made and the goals conceded. Also interesting is the fact of clean sheets, but certainly this is something rather reflects the defensive work of the whole team, so the day that everything was done while the goalkeeper does not have to pick up the ball on any network time, but in the long run, what guarantees success is to fit the smallest number goals as possible. If also the goalkeeper has to make many interventions will be receiving valuable information, which is that the goalkeeper corrected numerous times defensive collective failures.
therefore take as the first part of this unique ratio the ratio between the goalkeeper and stops the goals conceded.
Now comes the where. In the world of football to promote the best players presents many circumstances to promote availability of the player, there is room in the destination club for a player like him, tactical systems to facilitate the ownership of this, and so on. In the case of the goalie is different for two reasons. The first is that all teams need a goalie, so if it is touted as a big team before other partners: A major clubs like to have their backs well kept. The second is that although very good, it might not have before playing for a better one. This case is evident in the case of national teams. When evaluating where so that we will take directly the number of entitlements of the player, because all good goalkeeper captures the goal tends to ad aeternam. And so we will reverse the number of defeats of the team, which will give us information twofold: On one side will give the team's defensive level and another will compensate us for not having taken into consideration the value of clean sheets, and a team that loses a few games, necessarily has to end many of them with a clean sheet.
The resulting ratio is:
Stops entitlements
R = ----------------------- ------ x --------------------
Goals Conceded defeats
ONLY ONE OBJECTION
Here where the ratio is short, elegant and immediately, there is little of a mathematical object, but if it the usual historical objection. As always we try not to ramble here who could be better but note who has actually been better in a given period. The ratio gives us some of that information, the other will come to apply it to the number of entitlements accrued in the last 3 years, as this is a security lapse that allowed data collection.
