CLEVELAND — Moments after the Eastern Conference championship banner was raised by the Cavaliers for the third straight time and the obligatory postgame interviews ended, Tyronn Lue slipped quietly away.

Cleveland’s coach ducked into the shadows, his preferred location.

“I don’t like the attention,” he said.

But Lue, once a journeyman point guard who steered the Cavs to an NBA championship last season, has grown more accepting of his frontman role. He’ll again be at center stage this week as Cleveland meets Golden State in the third installment of their title trilogy.

If the unassuming, easygoing Lue had his preference, the teams would duke it out for the Larry O’Brien Trophy on a playground court in a stifling hot gymnasium, with only a handful of onlookers present. A student of the game, he’s old school with a fresh perspective.

Of the many juicy subplots between the Cavs and Warriors, one that frequently goes overlooked is Lue, the former assistant who has blossomed in no time into one of the league’s brightest young head coaches and a playoff savant.

He’s 28-6 in two postseasons with Cleveland. His players credit Lue’s soothing, steady influence – on and off the floor – as nearly as vital to their success as a clutch Kyrie Irving 3-pointer.

“It’s just his level of calmness no matter what’s going on,” LeBron James said following practice. “He always talks about, at the end of the day, he’s already won in life, so whatever else happens after this is extra credit. And I feel the same way. That’s why I relate to him so much. Lose here, or you win a game here, it’s like, ‘All right, cool. I’ve already done so much more than anybody ever gave me credit of doing or thought I can do, so there’s no reason to get too high or too low.’

“So it’s the even-keel mentality about our coach and it definitely helps us as players when we’re going out into a war.”

Lue has been preparing for the biggest battle of his basketball career this week.

From the moment he returned home from Boston following the Cavs’ win in Game 5 of the conference finals, Lue has immersed himself in the Warriors, a virtual All-Star team featuring two league MVPs (Kevin Durant and Stephen Curry), a dead-eye shooter (Klay Thompson) and a triple-threat performer (Draymond Green).

Lue is a stickler for detail, and he won’t cut any corners preparing for another dance with the Warriors. He’ll have the Cavs ready, and they can also count on him to keep them relaxed.

“When you’re prepared and you do the best you can do and you put it out there on the floor, you’ve just got to live with the results,” Lue said.
