“Practice makes perfect,” Cancar said, emphasizing he tries such shots a lot in workouts.
A video review showed Doncic stepped out bounds before his second-quarter step-back 3, and since the teams were already off the court, the game had to be picked up from that point after the break.
Denver coach Michael Malone put Cancar in the game, and he hit the running 53-footer from near the right sideline after taking the inbound pass. Denver trailed 56-55 at halftime instead of 59-52.
“We call him half-court Vlatko,” Malone said. “That’s why I put him in. The guy is uncanny with his ability to make those shots. For him to do it in a game setting like tonight, I really felt like it changed the game.”
Bones Hyland scored a career-high 29 points, and Porter Jr. had 12 with his only made 3-pointer in five attempts providing the final scoring.
