Hate to say it but it looks like 247's BB ratings are as out of whack as the football ratings. I can understand the football disparity because 247 doesn't give much credit beyond the first 16 players in a recruiting class, but in BB how do you explain so many of the 247 composite ratings being so much higher than 247's alone?

In Damian Jones' case it's favorable to Vandy, but I would like to understand the methodology.

Thanks.

I think the team rankings are different than the player rankings. The player rankings don't incorporate any sort of Gaussian model. I think the player rankings are just an ordering of the scores of the individual players, either the 247 score alone, or the composite score (the 247 score averaged with the others). If there's a disparity between the 247 ranking and the composite ranking, that simply means that 247 liked a recruit better than the industry average. A player could end up with a lower composite ranking if there is less of a consensus on how good he is.

Yah, who knows. The player rankings imply a deceptively high level of precision. Is the 28th person really quantifiably "better" than the 29th person in any objective or subjective dimension? Especially if those two players are evaluated by different scouts? The other problem with ranks is they don't show how bunched together players are. There may be relatively small differences in the players ranked 1-10 but then a big difference between them and the guys ranked 11-20, or whatever.
