I have to say that I'm disappointed with Rivals in some ways (although I know the other sites do the same thing): our four new commits just ended up getting the obligatory 2-star, 5.2 rating, because they signed with UConn and not someone else. Johnson got a 2-star, 5.4, but only because he's from Florida (so they gave him the extra 0.2 RR).
I'm quite sure that none of the four got a real look from Rivals, so they fill in the blanks. I guess you have to fill in something, but I hate that they flat out generalize their ratings based on who they sign with...
