For now, the only time Kentucky has won in a matchup in which the Wildcats were either ranked lower or as a team unranked in the AP poll was when facing a fourth-ranked Cardinal squad in December 2005.

Kentucky, ranked 23rd, upset the Cards 73-61 at Rupp Arena in a game dominated by then-sophomore point guard Rajon Rondo. He scored 25 points and dished out seven assists and was virtually un-guardable. While many were questioning Rondo's NBA future because of his lack of a jump shot, U of L coach Rick Pitino said in his postgame comments that Rondo would be a great pro because nobody could stop him from getting where he wanted to go with the ball - something that rivals of the Boston Celtics would surely acknowledge today
.
If Kentucky wins today, I think it might take a similar kind of performance, in which a player with big-time skills picks that day to showcase what he can do at the next level. And to me, Alex Poythress would be the most likely Kentucky  player to fill that role on Saturday.

Poythress doesn't have Rondo's point-guard game but the freshman big man could certainly assume the role of hardest-to-guard player on the UK roster, with his combination of inside-outside skill set.
