Jacque Vaughn was never worried about Joe Harris.

The Nets’ coach was convinced that his sharpshooter eventually would start hitting his target. Even during a miserable four-game stretch a few weeks ago in which Harris shot 3-for-24 and was taken out of the starting lineup, Vaughn was impressed by the way he was handling his struggles.

“You just love that he’s a teammate of yours,” Vaughn said. “I think when we first talked about it, I was extremely confident that Joe would eventually start making shots. It’s because his preparation is professional, because his approach is professional.

“It’s because he cares about the other teammates more than himself, and he shows that by being in the right position defensively. The biggest thing is sacrificing his body and boxing out. It’s the little things that don’t show up in the stat sheet . . . It was a matter of time and he’s still got some room where he’ll make some more shots for us.”

Harris, who missed most of last season after undergoing two ankle surgeries, started his third straight game Sunday and had 13 points and six rebounds in the Nets’ 103-92 loss to the Celtics.

In his previous three games — all Nets wins — Harris scored 17, 14 and 17 points and shot 16-for-29. In the Nets’ win over Toronto on Friday, he was 6-for-8, including 5-for-7 from three-point range.
