UK has signed the #1 class in the nation several times since I've followed the Wildcats (starting in 1966).
The first #1 class was signed in 1971 (Grevey, Conner, Flynn, Guyette, et al). The 1972 class consisted of Roger Wood, David Miller, Reggie Warford, Marc Moseley, and Jeff Ray.
The next #1 class was in 1979 (Bowie, Hord, Minniefield, Hurt, et al). The 1980 class was rated almost that high, with Bret Bearup, Jim Master, Melvin Turpin, and Dicky Beal. That's the exception to a trend, I think.
Next #1 class was in 1984 (Davender, Madison, Lock, Jenkins, et al). The 1985 class was Irving Thomas. Period.
Then comes another #1 class in 1988 (Kemp, Mills, Woods, Farmer). The 1989 class was Jeff Brassow and Henry Thomas.
And then, another #1 class is signed in 1992 (Rhodes, Delk, McCarty, Prickett, Dent). The 1993 class was Jeff Sheppard and Anthony Epps, with transfer Mark Pope added in the summer.
The final #1 class (prior to 2009) was signed in 2004 (Morris, Crawford, Bradley, Rondo, Sparks). The 2005 class was Rekalin Sims, Jared Carter, and Adam Williams.
A clear trend is evident above. The year following a #1 recruiting class often sees a big drop-off in recruiting.
Will that pattern get broken by Calipari in 2010? I think so but we'll see what happens.
