Not many coaches can say it, but John Calipari has been in this position before.Twice before this season he’d coached teams to 26-0 starts, experience he’s calling on as Kentucky set a record for the best start in program history on Tuesday night.It’s with that in mind that Coach Cal has changed his approach to coaching through mistakes.”I would have, you know, we keep winning, we’re up 18, I’m not screwing this up,” Calipari said. “Well you are screwing it up if you don’t correct. You are screwing it up if it happens in March and you let it go in February, shame on me.”For that reason, Calipari didn’t sound much like a winning coach after the top-ranked Wildcats (26-0, 13-0 Southeastern Conference) won at Tennessee (14-11, 6-7 SEC), 66-48. He isn’t letting mistakes go by without comment.Take Devin Booker for example. The freshman sharpshooter scored a game-high 18 points and added a career-best seven rebounds. He played good defense for good measure as UK held Tennessee to 37.5-percent shooting – including 17 points on 25-percent second-half shooting – but Calipari was looking for more.”Yeah, but he missed a bunch of shots,” Calipari said. “And I was getting upset because I kept saying we wanted to start the game posting the ball. So what did we do? We shot 3s.”UK made just 5 of 22 from 3-point range, but the Cats rebounded more than half their overall misses to make up for it. However, the fact that Tennessee had 19 offensive rebounds to UK’s 17 did not escape Coach Cal’s notice.”Well, let me say this,” Calipari said. “We didn’t outrebound them, and they got 19 offensive rebounds and there was a clip with three minutes to go where they got five offensive rebounds in a row. So, we have some work to do.”In Calipari’s mind, the same goes for UK’s two-headed point-guard monster of Andrew Harrison and Tyler Ulis. The pair combined for 22 points, eight assists and just one of UK’s 11 turnovers, but they heard from their coach as well.”I was on Andrew because he wasn’t attacking,” Calipari said. “I said, ‘If you don’t attack I’m not putting you in the game. I don’t care if you turn the ball over. When you catch it if you just pass it, you’re coming out.’ Then, when he attacks, Andrew, now we got he and Tyler both attacking, we’re coming running downhill at you, and we become the aggressor.”That mentality, to Calipari, is what it’s all about.”That’s why I keep telling them, you’ve got to come out and play,” Calipari said. “If you’re not attacking, I’m taking you out. You can say that I’m messing with you but I don’t care what you say, but you’re not going to play. Because that’s the way they’re going to get us.”Aggressiveness wasn’t the problem for Karl-Anthony Towns, rather controlling it. The reigning SEC Freshman of the Week played just a minute in the first half after picking up a pair of fouls that Calipari says can’t happen come tournament time.”I was just really disappointed in those fouls, and they were fouls,” Calipari said. “I mean, they were just a plain push – ‘What are you – why would you do that? Are you going to do that in March? Is that the play you’ll make in March? Then foul a shooter?’ And he fouled him. So, there are things we have to know and grow from.”To the outside world, the Cats’ pursuit of perfection defines them. There are ESPN commercials about it and all. But to Calipari, it’s all about that improvement. Whether UK falters in game No. 27 as UMass did in 1995-96 and Memphis did in 2007-08 matters little. Getting to and winning game No. 40 is what counts.”I’m telling you, we’re playing to get better,” Calipari said. “If that means we win more games, that’s fine. We are playing to get better. There are areas of offense we’re focusing on and there’s areas of defense we’re focusing on. And that’s what we’re doing.”And don’t doubt the Cats have accepted that challenge.”When Coach really says this is like a wolf pack, this is a wolf pack,” Willie Cauley-Stein said. “Like, we’re trying to be something special. So every day we’re trying to make each other better and that’s powerful. That’s what–you know that’s the path we’re on and we’re going to continue to be on that path, so, I mean, that’s the biggest thing I can tell you.”
