Tristan Thompson's three-point play with 2:39 remaining got Cleveland within 104-94. But the Jazz got three chances on their next possession, with Gordon Hayward converting on a short jumper. Kanter then followed with another basket to bump Utah's lead back to 14.
Kyrie Irving added 18 points with nine assists for Cleveland, but started 1 of 7 from the field before finishing 7 of 20.
Afterward, he expressed frustration.
"When our guys want to get it going, we just don't," he said. "We talk about it. Then teams make shots and we just don't respond."
"Coming out in the third and fourth quarter, we just get soft," he added, saying he was trying to make plays for his teammates.
Waiters said the Cavs "let this one slip away" in the third quarter.
"That's where we've had trouble all year is in the third quarter. We just got to stay the course," he said. "Come out and be aggressive and do the same thing we did in the first half in the third and fourth quarter."
Former Jazz swingman C.J. Miles added 12 points in his return to Salt Lake City, but shot 4 of 11, including 1 of 6 from 3-point range.
"It was good to see everybody," said Miles, who still has a home in the area and received a warm reception with a few boos mixed in. "It definitely brought back some memories. I wish we could have come out with the victory."
He said the Cavs got a little "stagnant" in the third quarter.
"We depend too much on trying to play one-on-one, which makes the game harder on ourselves."
The Cavs shot just 41 percent and were outscored 46-36 in the paint and dominated on the break.
Plenty of credit goes to veteran Jazz point guards Jamaal Tinsley and Earl Watson, sharing time in place of injured Mo Williams. They pushed the pace and finished with a combined 13 assists.
Tinsley started a 9-0 third-quarter run with a layup and Al Jefferson (14 points, 11 rebounds), capped it with a powerful dunk after faking out Tyler Zeller.
Irving's 3-pointer tied it at 43 with 3:31 left in the half.
But the second quarter belong to DeMarre Carroll, who had nine points on 4-of-5 shooting, with two rebounds and a steal in eight minutes to give Utah a five-point lead heading into halftime.
"They are an aggressive basketball team," Scott said. "I thought the first half we matched that and they second half we were overmatched."
