    Don't remember who/where they asked for this, but here's the link to the 247 only rankings. https://247sports.com/Season/2019-Football/TeamRankings/

    You can also just remove the word "Composite" from the url when viewing the composite team rankings and end up on the above linked page. Why 247 doesn't have a single feature on their own website that directly links to this active page promoting their own rankings, is one of the many things that are incredibly asinine about this company.

    Thank you for finding this, I was curious

    What's important:

    UW Avg. 90.7
    Oregon Avg. 90.04

    And by 247 we are 7th!!! in the country in avg. Player rating
    I think both are helpful. I like to use the composite for broader looks at recruiting as it goes on, plus it updates more frequently since it's managing three dynamic inputs. But I always like to qualify deeper analysis into our numbers with the 247 rankings/ratings.
    It's more than three inputs
    Three consistently updating sources of info...you get the point
    It's still more than three. There's no way you can get the comp rankings out of just their rivals, ESPN and 247 rankings. They are using some other rankings as well.
    Per their website this is how they get the comp team rankings. So yes it's technically more than three inputs but it is using data from only the three recruiting sources.

    The Formula

    where c is a specific team's total number of commits and Rn is the 247Sports Composite Rating of the nth-best commit times 100.

    Explanation

    In order to create the most comprehensive Team Recruiting Ranking without any notion of bias, 247Sports Team Recruiting Ranking is solely based on the 247Sports Composite Rating.

    Each recruit is weighted in the rankings according to a Gaussian distribution formula (a bell curve), where a team's best recruit is worth the most points. You can think of a team's point score as being the sum of ratings of all the team's commits where the best recruit is worth 100% of his rating value, the second best recruit is worth nearly 100% of his rating value, down to the last recruit who is worth a small fraction of his rating value. This formula ensures that all commits contribute at least some value to the team's score without heavily rewarding teams that have several more commitments than others.

    Readers familiar with the Gaussian distribution formula will note that we use a varying value for σ based on the standard deviation for the total number of commits between schools for the given sport. This standard deviation creates a bell curve with an inflection point near the average number of players recruited per team.

    Below is a graphical representation of how our formula works. You can see that the area under the curve gets smaller both as the rating for a commit decreases and as the number of total commits for a school increases. The y-axis in this graph represents the percentage weight of the score that gets applied to an overall team ranking.




    Where I have seen confusion by people on this board, and this may not be applicable to you @HillsboroDuck, has primarily been around the composite player rankings. People look at the rankings of the three sites, see a kid is ranked number 25 on espn, number 50 on rivals and 100 on 247 and then are surprised when the kids is ranked like 28th on the composite.

    But they aren't creating the comp player rankings based off where they are ranked on each site. Instead they are using the actual ratings of each player. And because each site has a different rating system (i.e 247 is a 1-105 scale, espn is like a 1-95 scale, rivals is like a 1.0-6.1 scale), they standardize those ratings systems so they are the standardizing a a score giving equal value to the three ratings and that's how they get a new composite rating (0-1, with up to four decimals). Basically a kid who gets a 105/95/6.1 would receive a 1.0000 composite rating. But a consensus number 1 in a given year may be rated like 101/94/6.0 and end up with some composite rating like .9995.

    Then they finally rank all those player ratings in order of value and that's how you get the composite player ranking. Essentially most people think that kids are ranked against each other, but really they get their own individual ratings and then are ranked in order. The composite does the same; complies a composite rating and then rank them in order.
    Good chit. I've seen some really weird Comp rankings that I'm not sure this explains but I'll definitely look for it in the future.

    Gracias.

    I didn't understand any of this.
    It checks out. I promise.



    What it doesn't do though, is use a weighted or normalized average, which would be hard with only 3 data points anyways but still. So ESPN is still definitely screwing things up for an objective rankings system.
