I thought that myself when I read that article that talked about a Data Scientist(tm)
In looking at our recruits by position group, it is apparent that some of the wide disparities between the recruiting sites are position group specific.
In other words:
Rivals loves our offensive line haul, 247 does not. Ave position ranking: 18.7 vs. 31.1 (I included Diamond and Garnett)
247 loves our defensive line haul, ESPN does not. Ave position ranking: 15.0 vs 29.8
ESPN loves our secondary haul, Scout does not. Ave position ranking: 23.3 vs 33.5
Everybody really loves our LB haul.
So, rather than choosing to love and hate various recruiting services based on my overall perception of their kindness to this years Michigan recruits, I was wondering if there might be some MGoBloggers with knowledge of the backgrounds of the guys making evaluations.
A little personal history of the guys (i.e. former positions played/coached, at what levels, etc.) and former predictive performance by position group of previous rankings would be hugely helpful to establishing what each recruiting service has as a "specialty."
