Freshman Bruce Ellington is the heart of South Carolina’s team as the leader in scoring (17.0 per SEC game) and assists (2.8 per SEC game). DeAndre Liggins is Kentucky’s best perimeter defender.

Liggins, who frequently guards the other team’s point guard (most memorably Louisville’s Peyton Siva), does not always defend the opposition’s ballhandler.
