I'm not sure I agree with this at all. I agree that that's how Calipari sells himself -- that he'll prepare recruits for the Draft better than anyone else. But I'm skeptical that's how it works out a lot of the time. I think a lot of the players who end up at Kentucky either don't improve at all or improve much less than their competitors at other universities. It's true that a lot of Calipari's recruits are high draft picks, but they would have been had they gone anywhere.
I don't think the Harrisons, James Young, Marcus Lee, Alex Poythress, Briscoe, to name just a few, improved their draft status at Kentucky. In fact, I'd argue their statuses regressed substantially. He's had some successes, to be sure, but the record is mixed at best. He's certainly not a master.
I don't think Calipari is completely transforming players in one or two seasons. With that said, no coach is going to improve the draft status of every high-profile recruit.
I picked out every Rivals 5-star recruit Calipari has signed at Kentucky to see how they fared in terms of being drafted. I picked one rankings service and selected an arbitrary rankings threshold for the sake of simplicity. It leaves out some Top 50 4-stars who did (Booker, Cauley-Stein) and didn't pan out. I was going for quick, not precise, but I think it gives us a fair idea.
I went ahead and included Murray, Labissiere, and Ulis as first-rounders, because they're universally projected as such for next month's draft. Counting those three, that makes 19 of 27 5-star recruits who were drafted in the first round.
It would be time-consuming to do that for every 5-star in the country over that span, especially since a lot of those guys have yet to enter the draft, but I'd bet anything they're not getting drafted in the first round at a 70.4% rate.
For the 2009 class, 11 of 25 Rivals 5-stars were drafted in the first round; that drops to 7 of 21 if you take out Kentucky players.
For the 2010 class, 13 of 27 Rivals 5-stars were drafted in the first round; that drops to 10 of 23 if you take out Kentucky players.
Kentucky's numbers may be skewed by a disproportionately high % of Top 5 or 10 guys, so it'd be interesting to look at just those recruits, too. For example, I count Kentucky going 12 of 17 on Top 10 recruits drafted in the first round. That may be close to the national average for Top 10 recruits, but it also means that a disproportionately high percentage of Kentucky's non-Top 10 5-stars (7 of 10) are first rounders (just looking at the non-Top 10 5-stars for 2009 and 2010, it's a lot more miss than hit). I suspect Kentucky stacks up well regardless of parameters.
Over an unusually large sample size for a single school, Kentucky puts a very high percentage of 5-stars in the first round. If you were an elite recruit, it would be hard to ignore those numbers. Cal may not coach you better than anyone else, but there is minimal risk of him tanking your draft stock.
