“Every game, every minute, every arena that I’m in, I try to just get comfortable and play at a proper speed,” Oladipo said. “I’m just trying to learn from every game and every moment.”

Oladipo and the Magic (1-2) faced an injury-depleted Mavericks (1-2) backcourt that started rookie Gal Mekel at point guard and Monta Ellis at shooting guard.

Making his third start of the preseason at power forward, O'Quinn struggled early but steadied himself a bit as the game went on. He scored two points on 1-of-6 shooting and collected six rebounds.

Tobias Harris, who scored 12 points, continued to play on the wing instead of at power forward, where he spent much of his time with Orlando last season. It's unclear whether Vaughn is giving serious consideration to bringing Harris off the bench once the regular season begins.

"I haven't settled on lineups, and I haven't even discussed that with him," Vaughn said.

"Pretty much we've just been putting him out on the floor in a position to see where his game is at right now and how he can help us. We'll always take the approach of what is best for the team. The great thing is he provides scoring whether he's starting or coming off the bench and provides us a person we can count on every single night."

Harkless finished with 16 points on 5-of-8 shooting.

A generously announced crowd of 17,136 saw fan favorite Dirk Nowitzki score 24 points.

The Magic need help protecting the rim, and Jones, 29, and Gladness, 27, might provide that.

“Today just happened to be my game where I was changing multiple shots, even if I didn’t block them,” Gladness said. “Like a coach a long time ago always told me, ‘If it’s going to the rim, you should be going after it.’ ”

With perhaps only one roster spot available, every preseason exhibition matters to Jones and Gladness.

Only five games remain.

Time is running out for both of them to make an impression.

What they did Monday should help.
