With recruit ratings I am convinced they just look at one aspect of the kid that they see as NBA ready, in this case Benny's bounce and athleticism, and just go "well if he develops x y and z, which he might do, then with his bounce and athleticism he would be a successful NBA player, therefore we will rate him high." I thought similarly with Carey and his high ratings. He had the athletic burst that would be fast enough for the NBA, just was lacking in literally everything else. Really what other explanation is there for either of those guys being so highly rated out of high school?
