On a roster full of stars, only Jarrod Polson would have been a more unlikely spark than Stacey Poole on Wednesday night.Although he played just two minutes in Kentucky’s 72-58 win over No. 23 Notre Dame, it was easily the most important two minutes of Poole’s young career at UK. His hustle sparked a Kentucky rally, built some confidence and moved him up the depth chart.”I think, at this point, I’m going to move to playing Stacey Poole now,” head coach John Calipari said. “He’ll move into the rotation in front of Jon Hood. Let him go (play). You’ve just got to come up with balls and be tough.”Poole presented some toughness in some brief, albeit rare, action off the bench. With Notre Dame pulling away late in the first half, Calipari inserted the freshman into the game.Up until that point, Poole had played just 15 minutes this year.Poole responded by draining an unlikely 3-pointer from the top of the key – his first career points – and pulling down an offensive rebound that led to a Brandon Knight layup. The key stretch was part of a 13-2 run that closed the 38-27 gap to a halftime tie.  “Let him get Jon’s minutes and let’s see if he can do better,” Calipari said. “He deserves an opportunity, too.”Though he was one of the least regarded players in this year’s mega recruiting class, Poole, a 6-foot-4 guard with a college-ready physique, signed with Kentucky as the 33rd-best player in the 2010 class, according to Rivals.com.
