Celtics’ crown is being fitted

That the Celtics have drained the mystery from the NBA Finals but they haven’t diminished the entertainment value – at least not for folks in these parts.

Teeth grinding, sitting in a lucky chair or wearing green underwear is no longer necessary. The Celtics are the NBA Champion-elect. The closing will be Friday in Dallas or Monday at the Garden.

Sit back, relax and enjoy.

There will be a storyline or two at play.

There is the ongoing debate as who is more valuable: Jaylen Brown or Jayson Tatum?

In this series, it has been Brown. Jrue Holiday is a qualified candidate.

Truth is, Tatum and Brown actually seem motivated more by hanging Banner 18 than staking a claim on being The Man. Contrary to the speculation of countless blowhards, they sound like they really do care about winning.

Don’t worry about declaring victory too early. Don’t chastise anyone for wearing whatever championship merchandise is already out there.

No team has ever rallied from a 3-0 deficit to win the NBA Finals. The last time the Celtics led 3-0 in a championship series was in 1959 when they swept the Minneapolis Lakers. That banner accompanied the franchise when Los Angeles stole the franchise from the Land of 1,000 Lakes, as Minnesota was nicknamed.

Those who have been puzzled as to how a team in Los Angeles would have the nickname Lakers, you’re welcome.

Watching the Celtics bench coalesce into a functional part of the whole has had its moments. Wouldn’t it have been a hoot to know what was rattling around in Kyrie Irving’s mind as he watched Sam Hauser drain 3’s.

And you know Luka Doncic would’ve been a bright shade of green had he watched Brown and Tatum glide to the hoop for monstrous dunks had he not been otherwise occupied.

Doncic had a running conversation with the referees over everything that didn’t go according to his plans. His whining bubbled over the first time a Celtic invaded his ample shadow, leading him to drop to the floor in an extra loud heap.

ABC’s coronation of Doncic as the most talented basketball player in any universe scraped bottom near the end of the halftime break Wednesday. A graphic artist must have put in overtime coming up with Luka the Magician.

As soon as Luka the Magician pulled a rabbit from a top hat, we suddenly raced to the facilities with an attack of severe queasiness.

He did make himself disappear with 4:21 left in the game, picking up his sixth foul. Someone needs to explain to him that NBA refs don’t respond well to non-stop whining.

Doncic’s post-game explanation, uncluttered and amplified: How can you call six fouls on me?

It’s sort of like when a cop pulls over a car and the driver begins the conversation, “Don’t you know who I am?”

The Celtics took full ownership of this series by squandering a 21-point lead. During one extended stretch of pure futility Dallas outscored Boston 22-2, a run that started in the opening minute of the fourth quarter.

Had that never happened, the Celtics wouldn’t have had the opportunity to rip out the Mavs’ spiritual heart and stomp on it.

A blown 21-point lead ended in a 106-99 win.

Warm up the Duckboats.
