Andrew and Aaron Harrison have decided to return to Kentucky for their sophomore years rather than enter the NBA Draft, a source told CBSSports.com on Friday. The development should again make the Wildcats the nation's preseason No. 1 team next season.

UK is now No. 1 in the Ridiculously Early Preseason Top 25 (and one).

The Harrisons' return was first reported by Yahoo! Sports' Adrian Wojnarowski.

The Harrisons are the fifth and sixth legitimate NBA prospects who have decided to return to U -- the others being Willie Cauley-Stein, Dakari Johnson, Alex Poythress and Marcus Lee. Combine them with an incoming class highlighted by Tyler Ulis, Trey Lyles, Karl Towns and Devin Booker, and John Calipari could theoretically use a lineup that looks like this:

G: Andrew Harrison
G: Aaron Harrison
F: Alex Poythress
F: Trey Lyles
C: Dakari Johnson

Reserves: Tyler Ulis, Willie Cauley-Stein, Karl Towns, Devin Booker, Marcus Lee
