Can evaluate all each of the circumstances that exist in a field to evaluate the quality of a plant? The answer is neither yes nor no, the answer is for what. According to what we have seen in the analysis of cost information relevant information is both more comprehensive, but one that is meaningful and accessible at once. One enters the central court in 12 plays, of which recovers the ball in 7, and 5 can ignore the player, but the latter, in 3 gets slow the progression of the attacker with which the central one or the goalkeeper made work to your advantage. On the climbs to top of 7 times have topped 2, one of them on goal, but the other 5 in 1 of them has resulted in a league of a partner who has been shot at goal advantage. Could you record this? Of course, but getting to that point of detail involves spending hours and hours to get a story that, ultimately, may not be as important. Indeed in our view reasonable to assume that for every 100 rises to top sometimes finish off and some not, some will go to doors and not others, that some foster second play, sometimes not, and is the overall balance which gives us information more definitive.
Suppose we want to calculate the weight of a human body if we put in the balance the skin, bones, muscles, viscera, fat and blood we will have a figure to 90% coincide with the full weight. And the tendons, and nerves, and mucous membranes, and bronchi, y. ..? Dozens of other elements have weight, but the first 6 and give us information relevant enough to be able to abstract the rest (obvious or estimated from those).
The list of the data I used to develop standards are
Player-Goals-Goals conceded by his team-
Goals conceded by the champions of the major leagues
-matches of his team-Shots
door
-player Yellow and red cards
-ownership of the player
All these data are handled in a time perspective of the past 4-5 years, which seems a very appropriate time slice to evaluate football careers, as most professionals working in about 3 decades, sometimes 2, sometimes 4.
Are there other data that they can grab to complete the calculations? No doubt! Hundreds of them actually: dodges attempted and made, received and warnings caused errors, turnovers, as companions, as rivals, and so on. But not all of them together would add the importance of those written before and 7 would change the analysis very cumbersome. It is more efficient to consider that either are not as significant, or are circumstances that eventually become compensated in some other occasions.
not intended here as an exhaustive analysis, but a relevant analysis that can be questionable but not contentious.
THE INDIVIDUAL VARIATION
The central player is an absolute necessity in modern football. Apart from the goalkeeper is the only one with a guaranteed place in the field. You can play without sides, not ends, with the midfield combinations that allow you to sacrifice a defensive or offensive midfielder, you can even play without center forward on the basis of accumulating versatile attackers. But you can not play without central.
However, unlike what happened with the midfielder, the central impact of an individual is less pronounced. If a team plays with the best possible midfield, his absence will cause serious problems with balance. Instead, the central best in the world can be relieved in a match for a good central without the team return too much change. Therefore, the first feature we see in the central is that his position is essential, but not occupying itself, something contrary to the case of multi-purpose hooks or the attackers, they are the ones that force the existence of such tactical position.
In the modern game spread attack defense is increasingly less tactical sense, because now wants everybody to defend and that all contribute offensively. But this does not alter the essential qualities of certain positions on the field, and center is one of them. With the same defense capabilities, a central is better if you can drive the ball, if you have a good shot or if it is working to give the initial pass to get the ball played, but the first thing to do is to defend a central. If secondary virtues are gained in return for the fundamental hindrances, the player will end up being relegated from the ownership. There are teams that they manage to give up two power play markers and a central-sweeper, but we hardly see two of these as a pair, let alone at the highest level.
Now to say that a center has nothing to say in his team's offensive game is quite another. The center is among the few players in the squad that is required at least one shot door game, they tend to be common in parts set pieces, in which they can contribute to its size and its technical spiker (as from small are taught to pitch), without running virtually risk. Many teams have a plus point to a handful of goals from set pieces, since even the least gifted team to the touch or the development equates to larger if a corner kick has two great finishers.
But ultimately their work is defensive, and the best will be the one central to their anticipations, their struggles, their failures even know to help your team snaps as few goals as possible. The optimum number of goals will vary from development of a game, a playoff or championship. In contrast, the optimum number of goals conceded is always the same: 0. Get with the least number of possible errors that can lead to dangerous set-pieces and / or receiving cards will be an added target worthy of esteem, but, contrary to what happened with the midfielder, a lack of accumulation of cards and even expulsion, can alter the team's ability to develop or attack but not defend, because as we said, the central player is an easily replaceable. When
and calibrate all of these qualities will take based on the number of goals against her in connection with those teams that have won the big leagues in the last five years. Will the number is average and the denominator the number of goals conceded by the team, thus facilitating a good number of goals conceded (ie, low), raise the value of the ratio. In the same ratio we will add two numbers are directly relevant and indicative. In the numerator, the average of goals conceded by the relevant teams, will add the number of goals the player, a fact that we have seen that, although not essential, if time is valuable. At the same time raising the value of the denominator in the amount of cards received (5-under for each red yellow). The mathematical reason why we add in the same ratio to evaluate these different figures without overestimating goals and cards.
However, this ratio may overstate the players who have participated little in the team's accomplishments. This time, instead of applying a correction ratio, which we will add the number of entitlements in the denominator, which will increase significantly the value of the ratio for regular players.
Therefore, the Individual would thus be Ratio:
THE ALTERNATIVE COLLECTIVE
The impact central of the team's offensive game is increased when it works in the end and it is not necessary to score goals, just make shots that, in most cases, not go out of doors for lack of ability of the central but as a result of pressure and support exchanges that occur in areas where set pieces. Getting to the ball and is, in itself, estimable. Because peer uncheck causes.
At the same time the central capacity to carry out its task without relapse in the fouls too, makes your computer except those set pieces that, ultimately, are chances to score even for tactical teams lower.
Thus we could establish the basis of the collective contribution to a ratio that valued the shooting of the player directly and inversely the misconduct. The best fire power to make fewer mistakes door.
For midfielders valorábamos your balance to the balance of points scored by their teams, but do the same with the plants would be unfair because his role in the field usually away from areas where the parties decide . But whether it would be valuable, and we will do, the share of losses of its equipment as these may never occur if the goal has been to 0, the optimum number Goal concede. Obviously these will be added to the inverse ratio to its value, we will add 1 to avoid infinite ratios, and the numerator will offset correction factor to avoid overestimating the players who have participated recently:
Cor = ownership / 35 If your computer
sum many defeats and he did not play a single match, the resulting quotient is 0. If played many games and not conceded defeat the ratio will be high. Therefore, the ratio
Collective becomes:
the summit of RELEVANCY: THE GLOBAL FACTOR
When dealing with elements that are added must be weighed each of them to ensure that the overall result is not suffering from overvaluation of one of its components. Not so when the issue is to use factors. Caution about it if we understand that a striker is better the higher the RI and RC, taken independently, the multiple of both grows with each one of them.
We have by convention that even in the case of the most selfish players on the collective factor has to be equally significant to the individual, but each one can weigh each of them as you deem appropriate.
Thus the overall ratio resulting the rating of how important the quality of a forward both individually and collectively on the basis of calculating the most significant would be:
RG = IR x CR x 100
As multiple quantities of less than 1, 0 usually yield very small numbers, has added 100 so that the resulting number is a number easier to retain.
OBJECT MATHEMATICS
While the process continued to produce a relevant and efficient ratio based on information brief but highly significant, the end result suffers from a certain imbalance due to the multiplicative nature of the factors. The order final results may seem consistent, but not differences in size.
Descriptive statistics provides us with a simple tool to adjust these deviations, which is the geometric mean. While the arithmetic mean is the average of N numbers by dividing the total combined N, the arithmetic mean is an average of quantities multiplied, but not the average ratio is used (which would have relevance proportional), but the square root or if the root N.
The final ratio would therefore like this:
2 ___
RF = \\ / RG
HISTORICAL OBJECT
This is the end of the process.
All aspects of the qualities of the plant have been taken into account to determine a ratio to give us the central value, but to find a figure that speaks to us of the importance of effective in a given period we will apply a multiplier to the result of adding their entitlements during the period the number of goals scored, and subtracting the number of cards.
