For a 15-minute period – halftime, to be precise – one could have concluded the Kentucky men’s basketball team had finally figured it all out.The Cats played with the type of toughness, physicality and killer instinct head coach John Calipari has been begging for all season. At the end of 66-60 win over Georgia, however, that feeling had all but evaporated. A halftime away from playing arguably its best half of the year, UK played one of its worst in the second half Saturday as the Cats narrowly held off the Bulldogs in front of 24,352 boisterous fans at Rupp Arena.Kentucky improved to 4-2 in the Southeastern Conference and climbed to within a half game of Eastern Division leader Florida, but the Cats stumbled down the stretch for the second game in a row.”We got pushed around again in the second half,” head coach John Calipari said. “I’m proud of our team.  I thought we played well … (but) we easily left ourselves in a position that we could have dropped this. There was no reason for that.”Calipari cited missed free throws and turnovers in letting Georgia hang around, but the reality is the toughness from the first half disappeared. After shooting 51.7 percent in the first half and extending the lead to as much as 17, UK hit only 31.8 percent of its attempts in the second half and allowed the Bulldogs to close within six points in the final two minutes.”It just goes along with us not playing a full game,” junior guard/forward Darius Miller said. “We’ve got to focus in on what we need to take care of or it’s going to come back and bite us. … I feel like I’ve said that a million times. We’ve just got to fix it.”Kentucky, at times, has looked like a top-10 team (see the Louisville, Washington and Notre Dame wins). At others, it’s looked like a team that sorely misses John Wall, DeMarcus Cousins and Patrick Patterson (see the Alabama, Georgia and Connecticut losses).The easy answer for the up-and-down play has been to tab it on youth. But according to Calipari, that’d be bailing out the players who are truly responsible.”This team has to be about Darius, DeAndre (Liggins) and Josh (Harrellson), our juniors and seniors,” Calipari said. “It’s got to be about them, what they accept, what they effect, and they have to be the guys making plays down the stretch, not freshmen. If our freshmen happen to do it, fine. But we can’t count on those guys.”Miller was the perfect example Saturday. In the first half, Miller played as dominant of a stretch as he’s ever played. In the process of scoring 10 first-half points, Miller banged with the trees down, grabbed loose balls, made the extra pass and knocked down a 3.”When Darius was in the middle, he went after people and he was aggressive,” Calipari said. “There was not a fade away. It was just boom, right at it.”With a little more than three minutes before halftime, Miller raced down the middle and nearly had the ultimate boom when tried a one-hand cram over Jeremy Price. He was denied with a foul, but it lit a fire underneath Miller and his teammates. “If he would have made that dunk, the whole gym would have gone crazy,” freshman guard Doron Lamb said. “At least he tried to dunk it so next time that guy knows he’s going to try to dunk it. That’s what coach wants him to do: be aggressive and try to dunk it every time he goes to the rack.”Calipari jumped off the bench and pumped his fists after the attempt and Miller flexed with a strut that fans have been begging to see. It was a glimpse of the “unleashed” player Calipari talks about so often.The problem was it didn’t show up for 40-complete minutes as Miller scored just four points in the second half and slowly faded out of the game (to his credit, Miller did have five second-half rebounds).”You’ve got to make the tough plays,” Calipari said. “You’re not missing a rebound, that’s one. Two, you’ve got to be really strong with the ball so you’re not getting balls ripped out of your hands.”One could infer Calipari was talking about a ball that was stripped from Miller late in the second half and an offensive put-back he allowed Trey Thompkins to get.Calipari was asked how veterans like Miller, Liggins and Harrellson – nice guys by all accounts – get tougher.”I’ve seen guys, they are boxers.  What a wonderful guy that is until he steps in that ring and he tries to rip the guy’s face off,” Calipari said. “You can be the nicest guy in the world, have a great heart and be a generous person, but when it’s time to battle and fight, you fight.”Despite the negative feeling from the second half, Kentucky didn’t lose Saturday. All things considered, there was a lot for Calipari to be proud of after the game. Among the positives were Lamb’s 19-point game and DeAndre Liggins’ all-around effort (11 points, two steals and one block).There was also a superb defensive effort against Georgia’s leading two scorers. Thompkins and Travis Leslie entered the game averaging a combined 32.6 points, but they were held to 14 total points and were 2 of 17 from the floor.”(We) did some good things,” Calipari said. And they also did some bad. It was the same as South Carolina and the same as Alabama. It’s cliché to say, but this team has been a tale of two halves recently and it’s been a tease.”This is good,” Calipari said. “We can be pretty good, and you saw it today. And then all of the stuff that we need to get better at, I’ve got it on tape.  I can show them.”  The bottom line, “We still won,” Calipari said.
