Heat: Slow starts won’t get it done

LAKE BUENA VISTA, Fla. — The formula that the Heat had backed themselves into using throughout this postseason wasn’t exactly ideal.

They were losing almost every first quarter, and winning almost every game anyway.

It’s not a sustainable plan, and the Celtics finally showed that in Game 3 of the Eastern Conference finals Saturday when they pulled off a wire-to-wire win over the Heat, not letting them put together their typical comeback. Game 4 of the East title series — with the Heat still leading 2-1 — is Wednesday, and the Heat are insisting that there will be more urgency at the beginning.

“We’ve just got to start off better,” Heat forward Jimmy Butler said. “I don’t think we started off anywhere near where we’re capable of. I think we dig ourselves a hole and try to fight back out of it. I think going into this next one, it’s up to the starting five to come out with a great start.”

Before Game 3, the Heat were 8-0 in the playoffs when trailing after the first quarter — after going 10-16 when put in that position during the regular season. In the 36 minutes of first-period action against the Celtics, the Heat have led roughly one-sixth of the time.

Butler is 1-for-6 in 29 first-quarter minutes in the series. Duncan Robinson and Goran Dragic are a combined 10-for-19; the rest of the Heat in first quarters against the Celtics are 11-for-46. The Celtics have won the first quarters by a combined score of 88-68, shooting 54% to the Heat’s 32%.

“Certainly, it would help to be able to get off to a good start,” Heat coach Erik Spoelstra said. “But you have to play good basketball more consistently when you get to this point in the conference finals against a quality opponent.”

Another wild stat is this: the Celtics have outscored the Heat 50-18 from 2-point range in first quarters so far in the series. And yet, somehow, the Celtics still need a win Wednesday to even up matters — or fall into the dreaded 3-1 series hole.
