John Calipari had just the right snapshot for how far Josh Harrellson has traveled in his development.Asked postgame if Harrellson would have made the type of game-saving plays he came up with Tuesday night a year ago, Calipari put things in perspective.”He wouldn’t have been in the game a year ago,” Calipari said. And yet there he was on Senior Night, his self-proclaimed “Jorts Day,” coming up with some of the game-defining plays when Kentucky so desperately needed a close victory. Harrellson blocked a shot, grabbed a steal and defended the final play in the last 24 seconds of Kentucky’s 68-66 win over Vanderbilt.”He was big time,” freshman guard Brandon Knight said. “He came up with big-time rebounds and finishes around the basket. He did a great job stepping up. Really, it just signified how he’s matured throughout his journey in college.”Perfect is such a loaded word, but it’s difficult to envision a more perfect night for Harrellson. For a guy who couldn’t even sniff the floor last season, he had one of the most impactful Senior Night games in recent memory.Harrellson finished the game with eight points, nine rebounds, four blocks and three steals. On his night to bask in the glory, Harrellson did the dirty work, too.With the trust from his head coach, Harrellson accepted the uninviting task of guarding Vanderbilt center Festus Ezeli for most of the game. A couple of weeks since the Commodores torched UK from behind the arc, Calipari decided to pick his battles with Vanderbilt and rely on Harrellson.”We gave up 2s so they weren’t shooting 3s,” Calipari said. “That’s how we played today.  We just made a decision. … We guarded the 3-point line a little differently than we did up there.”That left Harrellson alone on the inside with Ezeli, who has quickly evolved into one of the league’s best big men. Ezeli got his — he dominated with a game-high 22 points and, as Vanderbilt coach Kevin Stallings said so precisely, was “kicking @$$” — but Harrellson held his own down the stretch.”What Josh did is plugged up the hole,” Calipari said. “I’ve not coached a player that’s gotten more out of his body, out of his talent, out of his athleticism as Josh Harrellson. There’s nothing more he can give.  … Here’s a guy that jumps that high (Calipari illustrates an inch) and had four blocks. ‘How did you get those? What are you doing?’ It’s just an effort, man, just a desire to go make plays.”Harrellson didn’t cry when he was honored at midcourt before the game, but there was a lot more to celebrate than just a big performance or a basketball turnaround. After the game, Harrellson revealed he will be the first person in his family to graduate from college.”I am setting a milestone for my family and setting goals for my nephews when they grow to go to college and make something of their life,” Harrellson said. Harrellson was also informed Tuesday that he’s been invited to the Portsmouth Invitational Tournament, an annual pre-NBA Draft camp that showcases the nation’s top seniors. What that means is, as crazy as it sounds, Harrellson will have a shot at the NBA.”You have to understand, that’s not easy to get in Portsmouth,” Calipari said. “It’s a combine for seniors. It’s the first players that (NBA teams) look at. He’s worked himself, and he’s been invited. A lot of good things (are) happening for him, and I’m proud of him, just happy for him.” Does it get much better for Harrellson? Tuesday was indeed Jorts’ day.”It’s definitely emotional just thinking about going through my last game ever in Rupp Arena,” Harrellson said. “The fans have been great to me. Everybody has been great to me. Everybody has had my back.”
