It was clear from the opening minutes that Kentucky just didn’t have the edge it so often has had this season.With underdog Columbia jumping out to an 11-0 lead in the opening minutes, the lack of energy quickly spread to the crowd.The Wildcats never did manage to find their fastball, but Trey Lyles was the player who came the closest to getting them there.”Great motor,” Calipari said of the 6-foot-10 freshman. “Great motor.”Lyles’ numbers as No. 1 UK overcame two 11-point first-half deficits to move to 10-0 against the visiting Lions with a 56-46 win don’t exactly jump off the box score, but his impact did. His seven points, 10 rebounds, two assists and two blocks would have looked better had he made a couple more shots from in close, but his approach was the game-changer.”I just went out there and played with energy and tried to help the team in any way I could,” Lyles said.With Tyler Ulis and Devin Booker out on Wednesday due to injury, UK’s two-platoon system couldn’t work quite as intended. Coach Cal said that contributed to the Cats’ inability to move from the malaise, but a second-half shake-up helped them take control after trailing by two at halftime.Lyles started the second half in place of Alex Poythress, his first-platoon counterpart, the latest proof of Calipari’s “it’s not communism” tenet with the system.”Boom, out,” Calipari said. “Trey, go. I mean, it’s not real hard. The way we’re doing this, the only thing I’m asking is, play with a high motor, really play with energy, clap, be enthusiastic, play.”Lyles, even with his McDonald’s All-American pedigree and months into his college career, has come to grasp exactly that.”That’s just what I need to do and what he wants from me,” said Lyles, who played a season-high 30 minutes. “I have to do that for the team, it’s what the team needs. I’m not the only guy. Marcus Lee does the same thing. Alex does the same thing. We all just have to contribute in some way.”Lyles’ biggest contributions on Wednesday came on the glass.With shots not falling – particularly not from 3, where UK hit just 2 of 17 – there were ample opportunities for offensive rebounds, but the Cats weren’t capitalizing as often as they normally do in the first half. At halftime, UK had just a 17-15 edge on the boards in spite of a significant size advantage.To turn it around, Calipari turned to a group that’s rarely played together this season, if ever.”Trey Lyles went after the ball,” Calipari said. “I went to a different lineup. Dakari (Johnson) and Karl(-Anthony Towns) weren’t getting balls, so I went with Willie and Marcus Lee and we started getting rebounds. You know, this was one of those games where Marcus and Willie were the two that broke the game open. With Trey and, you know, the two guards with Derek Willis. Those seven broke the game open playing that way.”The stretch in which they did it came from the 16:18 mark of the second half to 1:39 left in the game. The Cats outscored Columbia 25-7 in that time, turning a three-point deficit into a 15-point lead. In the process, they paved the way for a 24-13 second-half rebounding edge.Lyles, of course, had a lot to do with that, though he’d also tell you he has plenty to work on.”I’m doing all right,” Lyles said. “I’m missing too many shots, but that’s on me to get in the gym and keep working on it. When shots aren’t falling I have to do other things such as rebound and play with energy.”He’s got that part taken care of.
