Recruiting services attempt to predict talent on the basis of past performance and current physical characteristics. Coaches attempt to win games by raising the level of performance through training, education, and conditioning, and as such have a better sense of how a recruit will grow. I would wager that a coach with a good eye for talent can spend an hour with a recruit and by observing his responses to coaching, can tell you far more about his potential than a recruiting service.
Which is to say that if a recruiting service gives a recruit high marks, he is probably a good bet...but...if they give him low marks, it doesn't mean that he won't be good, it just means that it hasn't been demonstrated yet. OTOH, if a good coach offers a poorly rated guy, rest assured that he sees potential that simply hasn't been coached up yet. It'll be very interesting to see where Dews and Moseley are at the end of this season. Gut tells me there will be some surprises.
It absolutely amazes me how amazing folks perceive Oregon to be, yet their star level is almost equal to ours. Seriously...either stars tell the total picture and we have a great chance of beating them...OR...stars are only one part of the equation, and coaches like Chip Kelly know how to find the *right* talent, not necessarily *best* talent, that can be coached into what they need. My money is on the latter, and on the fact that when Butch and his staff look at a kid, they see something far different than a recruiting service sees.
