John Calipari can sense the narrative changing. The season began with incessant talk of Kentucky’s platoon system and whether it would work, but the way the Wildcats are playing shifted the talk to defense.Calipari, however, wants to press rewind. He wants to go back to the platoon talk, though with, as he would surely put it, a tweak.”The story, everybody wants to talk about defense, they all want to talk about the energy, the blocked shots and the length, and the story is you have 10 guys sharing minutes,” Calipari said. “That’s the whole story in a nutshell.”No offense, Coach Cal, but this team’s story can’t fit in a nutshell, not with the way the Cats have been smothering opponents.The latest victim to succumb to UK’s waves of depth and athleticism was UT Arlington. Top-ranked Kentucky moved to 6-0 with a dominant 92-44 victory, holding the visiting Mavericks (3-2) to 27-percent shooting and a mere 0.611 points per possession and leaving yet another opposing coach raving, this time about exactly the topic Calipari wants everyone talking about.”They played the game the right way, that’s what is really impressive, to be able to get all of those NCAA All-Americans to play together as a team with 10 different guys, that is impressive,” Scott Cross said.But that defense though.UK allowed just 12 points in building a 43-point halftime advantage, the second-largest in school history behind only the 44-point lead the 1996 team had on LSU on the strength of an 86-point explosion. Astoundingly, UT Arlington made just four field goals in 32 attempts, compared with eight blocks for the Cats, as UK closed the half on a 42-5 run.The performance would have been more remarkable if it wasn’t so, well, commonplace for this team.Six times in 12 halves now, UK has held its opponent under 20 points. The Cats have not yet allowed 40-percent shooting from the field in a game this season and opponents are shooting just 28.7 percent from 2-point range, good for second nationally. UK has 60 blocks to boot, and at least seven in every game this season.”This team has a chance of being one of those teams you talk about defensively, like of all time, if they choose to be,” Calipari said. “But they’re going to have to choose to be that.”It seems they’ve already made that choice.”Coach is a defensive guy,” said Karl-Anthony Towns, who had his first double-double with 13 points and 11 rebounds. “He wants our offense to just (feed) off of our defense. So that’s the biggest thing for us.”Towns, who upped his team-leading total to 21 blocks with three against UT Arlington, can remember hearing the old “defense wins championships” cliche throughout his youth, but it took coming to Kentucky for it to sink in.”You’re told that all the time in high school and middle school,” Towns said. “You go to camps and stuff. But you don’t really see that happening until you’re in college. That’s really the biggest thing. We’re realizing that probably our biggest strength is our defense.”Calipari may have been the one who got the ball rolling with the defensive emphasis, but the players have taken over pushing it down the hill.”I wouldn’t say it’s Cal that’s getting us into it,” said Devin Booker, who has made 12 of his last 17 3-point tries after pouring in 19 points on 5-of-6 shooting from deep on Tuesday. “It’s us as a collective group, you know. We just want to lock teams down. We take pride in it.”Booker and the Cats have quite a bit to be proud of, having allowed 72 points in their last two games combined. Seventy-eight Division-I teams are allowing 72 points per game or more on average this season.For a team with 10 players among ESPN’s top 100 prospects for next June’s draft to sustain the focus necessary to do that to two admittedly overmatched opponents, not to mention holding then-No. 5 Kansas to 40 points, is nothing short of incredible.Uh oh, Coach Cal heard that.”I’ll come back to this: In this day and age, every one of these kids has pro aspirations and pro potential, and they’re draftable players, and they’re doing this for each other,” Calipari said. “This is crazy. That’s why I say, for anybody in our society, where everybody talks about the me and mine and narcissism and all that, why wouldn’t you root for this to happen and be good? I don’t understand why you wouldn’t root for this?”The Cats become even harder to root against once you hear Towns navigate his way around an extended metaphor expertly cooked up for Thanksgiving week.”I would say that if your group is doing what it’s supposed to do, then everyone should eat,” Towns said. “That’s the biggest thing. There’s a lot of food out there to go get. All you gotta do is go grab a plate and just go get it. That’s the biggest thing for all of us. We have the utensils.”How does UK’s defense fit into mix?”It seems like the buffet line starts there,” Towns said.
