Celtics need best version of Irving back

* Tonight on TNT: Bucks vs. Celtics (7 ET)

BOSTON — The Boston Celtics are looking forward to getting guard Marcus Smart back, possibly as soon as Game 4 against Milwaukee Monday night at TD Garden.

They would be better served, however, getting guard Kyrie Irving back.

The Irving who led Boston to its victory on the Bucks’ court in Game 1 of the Eastern Conference semifinals series was the latest, greatest iteration of the six-time All-Star point guard. Irving scored 26 points, passed for 11 assists and showed such maturity in orchestrating Boston’s attack that, even for a guy who has been on the national stage as long as he has, it seemed like some sort of breakthrough performance.

That guy, though, exited this series some time in the 48 hours before Game 2. Kryie 3.0 became Kyrie uh-oh.

Irving’s play looked rushed, detached and not at all mature. After hitting 12-of-21 shots in the series opener, he shot a combined 12-of-40 in Games 2 and 3 as the Celtics dropped both. They gave back the homecourt edge they had snatched with the opening victory and now need to win Monday just to force a best-of-three mini-series with two in Milwaukee.

Irving had a plus/minus rating of minus-26 in the two Celtics defeats. And most disconcerting, the player who arguably is the NBA’s best at making difficult shots seemed bent on making his shots difficult. Too often he went solo, didn’t probe for something better, didn’t spot or even look for another option.

Irving and Boston coach Brad Stevens had a conversation off to the side after the Celtics’ practice Sunday afternoon of moderate length. Afterward, each spoke with reporters. The point guard wouldn’t share what they discussed, while the coach deftly sidestepped the question.

“We just wanted to spend 15 minutes talking about the objection of the Kentucky Derby,” Stevens said. “How that could possibly have happened. And so we just created a conversation as long as the objection, and that’s what we discussed in great detail.”

Not likely. Stevens probably talked with Irving about some of the things the coach had said to reporters Saturday and Sunday: the need for the Celtics not to settle and not to succumb to whatever chaos Milwaukee’s defense was instigating by getting chaotic themselves.

For two days, answering various questions, Stevens has steered the discussion to Boston moving the ball as the surest way to high-quality shots.

“One of the things that we have to do as a team is just make those right reads off the first drive,” Stevens said, “and then go from there. We do have to do a better job of getting the ball to the second side of the floor, to the third side of the floor, and hopefully that includes as many paint attacks as possible.”

The Bucks’ unveiled a switching style of defense in Game 2, something they hadn’t done much all season. Too often, Irving’s eyes lit up seeing center Brook Lopez or forward Nikola Mirotic isolated in front of him, and the tunnel vision that triggered didn’t even generate the best shots for Irving. Too seldom, the Celtics failed to get Milwaukee’s defense shifting left-to-right, and back again.

“We have to make sure we’re patient in getting the best looks,” Stevens said Sunday. “That patience doesn’t mean you ease into it. You have to work really hard and be patient against these guys. Because they do a great job of covering up the paint.”

Celtics players made only 9-of-19 attempts inside 5 feet, a feeble rate by NBA standards. Lopez has been one of the league’s best defending the rim this season, and Giannis Antetokounmpo has the mobility to guard his man away from the hoop and still help inside.

Admirably, Irving has been willing to shoulder responsibility, flatly stating after the Game 2 loss: “This is what I signed up for. This is what Boston traded for me for.” After each game, he has given detailed breakdowns of what’s gone right, what’s gone wrong and, most important, what he planned to do in the next game.

It’s just that his most recent results haven’t matched his pledges.

The Celtics have more talent than the Bucks, and more players capable of carrying them offensively through a game or just a pivotal stretch. But those scorers, from Jayson Tatum and Jaylen Brown to Al Horford and Gordon Hayward, are dependent on Irving finding them and delivering the ball in a rhythm.

Admittedly, Boston has to cinch things up defensively. Averaging 110 points ought to be enough, if you’re not getting blistered at a 39-percent rate from 3-point range while sending your opponents to the free throw line an average of 30 times nightly.

Irving blamed all those stoppages for stealing transition opportunities and generally messing with the Celtics’ offense. Even so, he must do what Stevens calls “controlling the controllables” and be his best self. He has gotten the better of his individual matchup with Milwaukee point guard Eric Bledsoe, but that’s not enough.

And yes, this is what he signed up for. The great unknowns of this offseason, as in Irving’s future whereabouts, could swing wildly on what happens in the coming days. And what he makes happen.

“I’ve got to be me. That’s the easy part,” Irving said Sunday. “The same mindset that I’ve always had. Being aggressive. Being patient. Being able to be aware of the time of the game and where I need to make my impact. Being able to be in the right defensive positions and being able to communicate with my teammates as well.

“That’s the easy part though. That’s the fun part, if you go out there and just allow the flow of the game to dictate your instincts.”
