Of course. Duke and UNCheat kids that come back are always a "different type of kid that enjoys college basketball" or the "college life". Funny how those two schools seem to attract kids that would rather stay at college than be paid millions of dollars, huh? Couldn't be that their coaches care more about keeping them around could it?
*sigh*
That's stupid.
Can't speak for UNC, but for Duke, just as with UK, the top recruits go to the league quickly. Guys like Rivers, Parker, Irving, Okafor, Ingram... the top 5 type talents at Duke tend to go after one year, same as UK.
Then you have the next tier of guys who might stick around longer. Guys like Allen (who was a top 25 recruit) or Jefferson from Duke, or Lee or Poy from UK.
Sometimes there are guys who don't fit that profile, like the twins, who were rather highly rated and still came back. It happens because they might be a little overrated in high school compared to what they can be expected to do in college. Sometimes you have guys who are NOT as highly rated who OVERACHIEVE, like Devin Booker.
Now, I would have to really look at this more deeply, but with just having a rough understanding of UK guys, I think Cal has more guys who either OVER or UNDER perform than K... Duke guys tend to perform about where their high school rankings would indicate. UK guys, I think, are a little more likely to either out perform or under perform according to their rankings. I don't know if this is true, but I think that is the case.
It is rare for a guy who is a top talent and top couple pick to come back. It doesn't happen at most schools in the modern era. It is silly to try to argue that Cal has some radically different approach than K when there are no facts to back that up. Both coaches care about their players, try to help their players succeed, and give the best advice they can for success in the future.
UNC is an entirely different animal, thanks in part to Roy's willingness to play age over ability, and thanks in part to Roy's apparent ability to just crush his guys development
