Expectations of the Wildcats (13-0) going unbeaten have risen through their nonconference domination highlighted by defeats of ranked schools such as Kansas, North Carolina and Texas. Coach John Calipari figures to provide plenty of challenges for his players during the break before they resume their pursuit of perfection. Concerns about the Wildcats' focus in their first true road game at Louisville were quelled thanks to cool performances by their freshmen, who combined for 39 points. Leading the way was 5-foot-9 guard Tyler Ulis, who received three stitches for a cut over his right eye after he scored 12 of his career-high 14 points in the second half to help Kentucky stay safely ahead. [...] while nine players average 14 to 24 minutes in the platoon system, with eight averaging between 5.8 and 10.3 points, Calipari sees room to work sophomores such as Dominique Hawkins and Derek Willis into the rotation to enhance Kentucky's depth.
