Things might look very different the next time the Miami Heat play at Kaseya Center, and not only because of the proposed new scoreboard.

With a 102-88 home loss on Monday night and a 3-1 deficit to the Boston Celtics in their best-of-seven Eastern Conference playoff first-round series, the Heat will only play at home once more this season after winning Game 5 on Wednesday night at TD Garden.

The Heat’s season is running out of time based on the lopsided scores of their last two losses, with the gap reaching a high of 28 on Monday night.

Out loud.

Coach Erik Spoelstra stated, “Our guys really want to get this thing back to Miami and have just a great game in front of our fans.” “The desire to perform well in front of our supporters is what drives our team to return here.”

Even though the Celtics lost center Kristaps Porzingis for the evening in the second quarter due to calf discomfort, the Heat were unable to capitalize this time after two 20-point losses in the series, one of which occurred on Saturday night in Game 3.

Whatever the case, it was more than just a night when Celtics guard Derrick White scored a career-high 38 points in the first half, helped by teammates Jayson Tatum (20) and Jaylen Brown (17).

Once more competing in Jimmy Butler’s (knee) and Terry Rozier’s (neck) injury absences, the Heat’s offense was insufficient, as Bam Adebayo finished with 25 points and 17 rebounds, Tyler Herro with 19 points, and Caleb Martin with 18.

“We’re entering the den of lions,” declared Adebayo. “Everyone is aware of the stakes.”

The fact that Heat youngster Jaime Jaquez Jr. was sidelined for the fourth quarter made things worse.

With only 22:10 remaining, Jaquez remarked, “It was just my hip.” “I felt my hip give in the first quarter of the third quarter.”

This continues to seem like a significant step backward after the Heat made it to the NBA Finals last season and the Eastern Conference finals two years ago. Heat president Pat Riley may soon be thinking about everything, including what might come next for Butler, Herro, and even upcoming free agents like Martin and Haywood Highsmith.

For the time being, the main goal is to force a Friday Game 6 back at Kaseya Center — even though the odds seem stacked against them on Wednesday night against the top-seeded Celtics.

Herro stated, “We’ll just focus on getting one game in Boston and working it out from there.”

Five Points of Heat from the Playoff Game on Monday Night:The Celtics jumped out to an early 15-point lead, led 34-24 at the end of the first quarter, and then stretched to a 53-36 advantage at the half.

The Heat only scored 35 points in the first two quarters of the game, as the Celtics extended their lead to 26 points in the third quarter and led Boston to an 81-59 lead heading into the fourth.

With 5:21 remaining, the Heat then mounted a comeback, winning 91-78.

However, Adebayo was punished for a flagrant foul with 5:04 remaining after pushing Tatum with the ball. From that point on, Boston extended their lead to 19.

Adebayo responded, “I don’t even know,” when questioned about receiving the fine. “We’re going to get past that.”

With just 16 total seconds of lead in their two home games in this series, the Heat lost their sixth straight home playoff game.

Spoelstra stated, “Offensively we struggled again.” “It is necessary to record a few points on the board.”
