Recruiting class 'rankings'

[notanative]

Do these several ranking 'organizations' take into account whether a team actually recruited a top prospect, or is it strictly 'these are the top prospects as I see them, and the best class is the one with the most of them in it?"

You know that these kids are so close in talent that if you're listed in the top 100 in the nation, you're a damn good football player. I mean, with what I've seen on film if I had to choose the top 5 players I would list them as this. Can't go wrong with anyof them.

1) Landon Collins.
2) DGB
3) Malcom Brown
4) Johnathan Gray
5) Mario Edwards

Some use "total stars", which means a team that gets more bodies is often ranked higher than a smaller class of better players.

Rivals, Scout and ESPN individually rank recruits.
ESPN ranks teams by the number of players from their 150 list.
Scout:How does Scout come up with the player rankings?

Scout works from the grass roots and then reports up. We have a Team of Scouts around the country including local scouts that work smaller areas that submit their rankings to a regional manager. The regional manager will compile the rankings from the local scouts in his area then submit his compiled list to the National Editors. A final conference call between the regional managers and the national editors results in a compiled list of national rankings.

Team Rankings

Team Rankings are a math formula that based on a player's rating and his rankings. 5-Star is a rating, No. 1 quarterback is his ranking.

5 Star = 200 points
4 Star = 120 points
3 Star = 40 points
2 Star = 20 points

The No. 1 player at a position is worth 100 points, counting down to the last ranked player at his position to 0.

For Example, assuming Scout ranks 100 quarterbacks.

5-Star, No. 1 QB = 300 points
4-Star, No. 10 QB = 210 points
3-Star, No. 50 QB = 90 points
2-Star, No. 75 QB = 45 points

The Team Rankings are compiled of the Top 25 players per class. Some teams will over-sign, but only 25 count towards the Team Rankings.



Rivals: Below is what I received from the person who initially put the formula together. He is a stats grad from Cal-Berkeley and computer programmer. It has been unaltered for the past 4 years. ****
It's a very basic formula, which I'm going to explain in general, and then show you what goes into each part:

H * ( n / ( n + m ) ) + L * ( m / ( n + m ) )
So, let's look at this in its most general form. The total points is the sum of H times something and L times something. Leave the somethings alone for a moment. What are H and L?

H = potential High score = 250 for every five-star, 140 for every four-star, 75 for every three-star, 20 for every two-star and 10 for every one-star
L = potential Low score = 18 for every five-star, 12 for every four- star, 8 for every three-star, 3 for every two-star and 1 for every one-star

WE ONLY LOOK AT THE TOP 20 SIGNEES for this part. We end up with two numbers, a High and a Low. A team's final score is going to be between these two numbers. I'll use Team Z for an example:

*******************
EXAMPLE: Team Z (2 five-stars, 17 four-stars, 8 three-stars, 2 two- stars). Team Z's top 20 recruits then are 2 five-stars, 17 four-stars, and 1 three-star, which gives them an H of 2955 and an L of 248.

Z's score will be somewhere between 2955 and 248.
*******************


OK, now how do we figure out where in this range the final score is?
Time to look at the other two elements of the formula:

( n / ( n + m ) ) and ( m / ( n + m ) )

The variable m is just a constant. We happen to use 50, but it doesn't matter. Changing it just changes the "spread" of the numbers...I picked 50 because it gave us nice-looking numbers without changing the actual places of the teams.

The variable n is the important one. This is the one that changes.

This is where the math gets a little more complex. Notice that as n gets higher and higher, then the expression on the left approaches 1 and the expression on the right approaches 0. As n gets lower and lower, the opposite occurs: the expression on the left approaches 0 and the expression on the right approaches 1.

So, shorthand: AS N GETS HIGHER, A TEAM'S SCORE APPROACHES ITS H. AS N GETS LOWER A TEAM'S SCORE APPROACHES ITS L.

When I try to explain this to people on the boards (which I don't do any more) I didn't want to just reveal the formula, so I asked users to envision a scale, on one end is a high number and on the other end is a low number. And a slider that slides between them, pointing to the actual number somewhere in between.

OK, so what goes into calculating n? Here's where all the factors come in that are just lifted from the old formula. The variable n starts out as 0. And then we add:

--Ten points for every commit in the Rivals100 from 1 to 10, nine points for every commit in the Rivals100 from 11 to 20, and so on down to one point for every commit in the Rivals100 from 91-100.
--The same for every commit in the Rivals100 Juco and the Rivals100 Preps, only we only go down to the top 50 on those two lists, not the entire 100.
--24 points for every commit that is the Number 1 player at an official Rivals Position Ranking.
--18 points for every commit that is number two, three, four, or five at an offical Rivals Position Ranking.
--8 points for every commit that is number six through number X at an official Rivals Position Ranking.

This last one varies by position. Each position has a different cutoff. For kickers, for example, we add 8 to n if a commit is ranked from 6 through 10. But at wide receiver we give it all the way down to 50. Every position has its own cutoff. I didn't dream up the cutoffs...I just used the ones that were there in the original formula, devised by Jeremy Crabtree in 2001.

--The last thing we add to n is the amount over 3.0 for the star rating of the entire class, times 100. For example, if your class is an average 3.03 stars, we add 3 to your n.
