Darius Miller, DeAndre Liggins and Josh Harrellson have had quite a ride in their time at Kentucky. They are entering their third seasons at Kentucky and have seen and been a part of success, failure and a coaching change.Miller, Liggins and Harrellson are the three remaining members of Billy Gillispie’s five-man recruiting class in 2008. In their first season, they were a part of a team that missed the NCAA Tournament for the first time in nearly two decades. In their second season, they were members of the supporting cast of John Calipari’s first UK team, a squad that returned the Wildcats to glory with a regular-season Southeastern Conference title, an SEC Tournament championship and a berth in the Elite Eight.Now, with UK having lost five players to the NBA, Miller, Liggins and Harrellson are being asked to do something that had previously been the responsibility of their teammates — they’re being asked to lead. While the three may not be as naturally inclined to lead as John Wall and Patrick Patterson, for example, Calipari is demanding they take a step forward.”I’m definitely trying to step up into that role and be more of a leader,” Miller said. “All of the other veteran guys with experience under Coach Cal are trying to do the same thing.”A leader must be unafraid of demanding the ball and making a big play. Calipari demands that his leaders fill the role of catalyst.”If you’re going to be a catalyst, our team has to know you show up every game,” Calipari said. “It doesn’t mean you make every shot, it means you have the same kind of mentality every time you play, and you figure it out however you feel.”However, leadership is a delicate balance, particularly under Calipari. That role of catalyst must be accompanied by servant leadership, a willingness of an individual to put the team before himself.”How about Patrick Patterson?” Calipari said, citing an example. “He scored less than the year before. He rebounds less. He goes from being the guy to one of the guys. And he goes from maybe being the 25th to 28th pick in the draft. By giving it all up, by servant leadership, by giving it up and sacrificing, he goes 14th in the draft.”With Calipari signing the nation’s top recruiting class for the second consecutive season, this year’s roster is comprised of another group of talented newcomers. For UK to meet expectations, multiple freshmen are going to have to play a major role from day one.  Miller, Liggins and Harrellson are going to be asked to sacrifice for the benefit of the team as well as play a major role in integrating the newcomers. Fortunately, they have experience from last year when they helped successfully do the same thing.”We went through it once, so it’s easier this time around,” Harrellson said. “You have to teach them what needs to be taught. You have to teach them right from wrong and lead by example.”Miller was quick to point out that Calipari helped matters by bringing in a group blessed with character as well as talent.”He recruited a great bunch of guys, not just players,” Miller said. “That makes it a lot easier, too.”While it is wise to avoid individual comparisons with last year’s team, there are many lessons to be learned from it.           “Will this team come together and share the ball and do the things they have to do to be their brother’s keeper?” Calipari asked. “Will you be your brother’s keeper? Will we have servant leadership which we had a year ago, where our leaders cared more about the team?”With experience from last year, the group of veterans understands the humility it takes to exhibit servant leadership. They, particularly Miller and Liggins, are working to develop the confidence it takes to be catalysts.One factor helping in that endeavor is the fact that Miller, Harrellson, and Liggins are playing for the same coach in consecutive seasons for the first time in their collegiate careers.”(Playing for Calipari for another season) will help me greatly,” Liggins said. “He’s a great coach, I fit his system well, and he’s a great motivator. I’m more relaxed, more confident, too.”Miller anticipates that the continuity from last season will allow him to focus on what is being asked of him as a leader, rather than learning a new system.”It means a lot to have that experience and know what to expect going into it,” Miller said.  “It’s different when you switch coaches with totally different styles of play. Playing for him again, especially the type of coach he is, makes it a lot easier.”No matter how talented a group of freshmen may be, there are going to be inevitable ups and downs. Last season, Patterson provided a consistent veteran presence that helped weather many of those downs. This season, Calipari will turn to Miller, Liggins and Harrellson to do the same.”I think we’ll be a different style, but we’ll get just as much done,” Miller said.
