UK's 2014 recruiting class was wildly underrated.
Not that the 2013 class lacked talent, but it wasn't what it was cracked up to be. Even Randle, who was a star, and probably still has that potential in the pros, is struggling to find his role in the NBA.
Every guy in the 2014 class, OTOH, was (at UK) and is (in the NBA, or Ulis at UK) as good or better than advertised. Towns is clearly headed to an NBA All-Star future, with MVP level not out of the question. Booker is the youngest player in the league, and he's clearly going to be around for a long time. All-Star isn't out of the question for him. Lyles probably won't ever be a star, but he shows all the signs of being a potential long-term starter.
