Not sure how much Calipari developed Booker in that one season he had him coming off the bench.
Come on. So he doesn't get your stamp of approval because he left after one year instead of three? That's kind of counter-intuitive, no?
Just look at what he did with that '15 class:
Karl Towns - #5 RSCI, #1 pick in 2015 draft and on pace to be one of the best players of his generation
Trey Lyles - #12 RSCI, #12 pick in 2015 draft coming off a disappointing sophomore season in the NBA after a promising rookie campaign
Tyler Ulis - # 18 RSCI, #34 pick in 2016 NBA draft who averaged 18 and 9 in his final nine games this season with Phoenix
Devin Booker - # 23 RSCI, #13 pick in 2015 draft and appears on his way to being an all-star wing
The guy is either really good at developing these prospects or really good at identifying them. It's never been as simple as hand-picking the highest ranked players and placing them on a red carpet to the NBA - the data suggests that more often than not these guys out-perform their peers and that's why they continue to choose Kentucky.
