Among UK's historical recruiting classes? It's hard to make a true determination, being that all of the historical groups can be judged by their accomplishments on the court whereas we haven't even seen Skal and company play a game together. If the current class, for example, ends up producing a future all-star in Skal or Murray, or if Briscoe ends up being a decade-long NBA player, the value of the current class will grow exponentially.
My best guess (apologies to Jon Scott for any glaring omissions or oversights).
#1 - 2013-2014 (6 McDonald's All-Americans).
#2 - 2009-2010 (Wall, Cousins, Bledsoe, Orton).
#3 - 2011-2012 (Davis, MKG, Teague, Wiltjer).
#4 - 1945-1946 (the core of a group that became America's first dynasty).
#5 - 1978-1979 (Bowie and friends).
#6 - 1995-1996 (higher if we count Anderson's transfer).
#7 - 2004-2005 (Rondo, Morris, Crawford, Bradley).
#8 - 1966-1967 (Issel and company).
#9 - 2010-2011(hard to argue against two current max players plus Terrence Jones and Lamb).
#10 - 2014-2015 (I see you Karl Towns).
#11 - 1991-1992 (Delk, Rhodes, McCarty, Prickett - two Final Fours and a national title).
#12 - 2015-2016 (the class with global impact?).
#13 - 2012-2013 (a group that featured WCS, Noel, Goodwin, and Poythress).
#14 - 1977-1978 (Kentucky's first Mickey Ds).
#15 - 1999-2000 ( Bogans, Stone, Estill, Stewart).
#16 - 1990-1991 (the Mashburn class).
I just ran this list over coffee time this morning. It's by no means exhaustive or overly analytical. Feel free to discuss and offer your own insight.
