re: Composite team rankings are a joke

247 actually came out at one point and stated that they give bumps based on what college signs the kid, and that since bama has a knack for sending kids to nfl in their system, the kids get bumped

Ron Sanders on auburn 24/7 put a post about what was explained to him regarding the algorithm they use. It absolutely makes no sense, and is flawed.

Eta: Here is the explanation

I know there have been several questions about class rankings. I just had a 15 minute conversation about it and this was the way it was explained to me:

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.

The 247Composite Rating is a proprietary algorithm that compiles prospect "rankings" and "ratings" listed in the public domain by the major media recruiting services.

Each player is awarded a value rating (e.g. Cowart's value rating is .9987). The 247Sports Composite Rating is based totally on that value - not on stars.

Stars are awarded based on a range within 247Composite Rating.
100 - 98 = Five-star prospect, 97 - 90 = Four-star prospect., etc. etc....

Each recruit is weighted in the team rankings according to a bell curve (Gaussian distribution formula), 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.

There's virtually no difference between No. 6 (Ohio State 279.83) and No. 9. (Auburn 277.69).
If you line up the top players in each class, you'll see that Auburn's top players are rated slightly lower (have a lower value) than the schools rated higher.

When graded on a bell curve, the difference is very clear. The formula hasn't changed in three years.

The bottom line: we're talking about fractions of points. Auburn signed an amazing class, among the best in the country. We'll find out in three to four years who really won National Signing Day 2015.
