There are about a dozen guys playing in the NBA right now who would disagree with that, and not all of them were sure-fire pros upon arrival.
You're riding the Wall/Davis/MKG wave. All those guys went where they were supposed to.
There's also:
Teague, the No. 7 talent in the class, went No. 29
Jones, the No. 8 talent in his class, went No. 18
Lamb, a top 20 talent in his class, went No. 42
Noel, the No. 1 talent in his class, went No. 6
Poythress, a top 10 talent in his class, is projected as a 2nd-rounder
Goodwin, a top 15 talent in his class, went No. 29
Randle, the No. 2 talent in his class, went No. 7
Andrew Harrison, a top 10 talent in his class, is projected as a borderline first-rounder
Aaron Harrison, a top 10 talent in his class, is projected as a second-rounder
Young, a top 10 talent in his class, fell outside the lottery
Johnson & Lee were considered top 20 talents, but are now looked at as borderline first-rounders
The only guys who substantially increased their stock under Cal are Bledsoe and, it seems, Cauley-Stein. And other than Davis, the guys he's put into the league - Cousins, Wall, Knight and MKG especially - all have the same exact flaws that were on display when they got to Lexington.
He is a brilliant recruiter. But he does not develop his talent, and most kids who go to UK cost themselves millions by doing so.
