TORONTO – Observations and other interesting notes from Sunday night’s 119-116 loss to the Toronto Raptors:

– There have been times in recent seasons when the burden on Jimmy Butler seemed overwhelming.

– There were times when the same could be said in recent years with Bam Adebayo and his amount of responsibility on both sides.

– And then you experience an evening like that and wonder if Tyler Herro could maybe get a little help.

– Herro carried the heat in the first half.

– Was active while others were anemic.

– And then, in the third third, a driving stop. . . that wasn’t it.

– Due to basket interference with Adebayo.

– And a precise pass for a 3-point shot. . . that wasn’t it

– When Duncan Robinson bobbled the ball out of bounds.

– Of course, this team wasn’t built that way.

– But for Adebayo it was a constant struggle to score.

– And for Butler it’s just not something every night anymore.

– Instead, Herro’s heroics have defined the best of the Heat so far.

— As he returns Monday to Boston, where he delivered a tour de force performance in the Heat’s only playoff win last season.

– Who had Herro as the Heat’s leading All-Star candidate in October?

– In December, who doesn’t?

– The concern is that he is also the only current candidate.

– All or nothing.

– His late 3-point miss in this game was costly.

– But also the player who put the Heat in this position.

– The Heat opened for the sixth straight game with a lineup that included Herro, Adebayo, Butler, Robinson and Haywood Highsmith.

– With this line-up the score is 4:1.

– Robinson was whistled for his second foul 1:19 into the game.

– The Heat’s options are somewhat limited with Nikola Jovic (ankle) and Josh Richardson (illness) not with the team.

– The Heat were without rookie center Kel’el Ware as the first-round pick from Indiana was sidelined with tendonitis in his right foot.

– Kevin Love and Pelle Larsson appeared together in the Heat’s first substitution.

– Terry Rozier followed.

– Then Jaime Jaquez Jr.

– With Alec Burks, early in the second quarter, making it deep for the Heat.

– That left Thomas Bryant and Dru Smith as the only available players.

– Adebayo’s first conversion from the foul line moved him past Rony Seikaly and into fourth place on the Heat all-time list.

– The double-double was the 201st of Adebayo’s career. Only Rony Seikaly (221) and Alonzo Mourning (205) had more with the Heat.

– The Heat hit 54 3-point attempts in their home win over the Raptors on Friday night.

– “We just want to have a profile that makes sense, the most sensible thing for our team,” said coach Erik Spoelstra before the game.

– But Spoelstra also emphasized that it can’t just be about 3-point shots.

– “We have said all along that one is not more important than the other,” he said. “We also have to be aggressive. We also have to have our paint attacks.”

– This time the 3-point volume was significantly lower.

– Raptors coach Darko Rajaković spoke about the Heat’s zone defense before the game for the second straight day.

– Miami is a team that plays in the zone quite often,” he said. “They play more than other teams, they have had success in this zone over the years.”

– So the Raptors brought RJ Barrett into the heart of the Heat defense and the former Knick went to work from there.
