Justise Winslow calls the group "the three dogs." It might not be as catchy as The Big Three, but it's a trio also not nearly polished. Still, when Winslow, Josh Richardson and Briante Weber have been on the court during summer league, good things have happened in recent days for the Miami Heat.

That again prove to be the case Tuesday, when the Heat improved to 3-0 at the Orlando Pro Summer League with an 84-68 victory over a similar group of rookies and young players from the Orlando Magic on the Magic's practice court at the Amway Center.

"When it comes to me J-Rich and Briante, it's just three dogs defensively," said Winslow, the forward taken out of Duke in the 2015 NBA draft. "And the way J-Rich has improved offensively with his shot, the way I've continued to improve, and the way Briante will as he gets a full year with the Heat coaches, it's going to be a lot for other teams, especially when we're out there all three of us together, pounding them.

"We've just got three dogs, I would say, when it comes to defense. J-Rich is so long. Briante is so long. And I'm not that long, but strong. When we're out there on the floor, we can really control things defensively, and then offensively we just play off each other."

Richardson, the guard taken in the second round a year ago out of Tennessee, paced the Heat's offense Tuesday with 22 points, shooting 6 of 9 from the field and 3 of 4 on 3-pointers, adding six assists.

"I love Josh's confidence," said Heat assistant coach Juwan Howard, who is coaching the Heat's summer-league team. "He's a competitor. And if you want to be a competitive player at a high level, you've got to have that edge about you, and he has that."

The edge was there Tuesday, even while playing at this offseason level of competition.

"I mean, since college, I've always kind of been a scorer," Richardson said. "So when I got in the league, it wasn't really anything different. Today they were just giving me looks and I was taking 'em."

Winslow added 15 points, albeit on 5-of-15 shooting, while Weber filled the stat sheet in the 40-minute game with nine points, 10 rebounds, six assists and six steals.

Howard said Weber, the undrafted rookie point guard added late during the regular season, is displaying the depth of his game.

"It doesn't surprise me when I look at a box score and I see out second-smallest guy led us with 10 rebounds," he said. "That's big. It let me know he's always around the basketball. He's trying to make sure that we get stops, we secure the ball and we're able to get out and run."

Weber also converted a dramatic alley-oop dunk in transition off a backboard pass from Winslow. He was called for a technical foul for hanging on the rim, but he said it only was because of fear of an awkward landing, after being sidelined for nearly a year following a devastating knee injury while a senior at Virginia Commonwealth.

"What the refs don't know," he said, "is I got a knee brace on for a reason and I didn't feel comfortable coming down right then. I had to protect my landing. So I pretty much held on a little longer. It's a long way down. Safety. I'm not trying to go through that again."

While Winslow was uneven from the field, he did make a 3-pointer off the dribble, an encouraging development.

"I want Justise to basically be a guy who's not thinking, just play basketball," Howard said. "I trust that whatever shot he ends up taking, I feel good about it. I know he's worked extremely hard on not only just his jump shot, but his overall game.

"He's trying to find way of improvement and how to get better as a ballplayer. So I am so happy for his development. And I think he has so much growth in him."

Richardson and Winslow had been given the Heat's previous game off, and could get one of the Heat's final two off this week, as well, with Weber expected to appear in all five.

The Heat now have Wednesday off, before a Thursday 5 p.m. game again a similar group of young players and rookies from the Detroit Pistons, who have 2015 first-round pick Stanley Johnson on their summer roster.

The Orlando summer league concludes Friday with championship-round play for all 10 teams, before the Heat move open to open their schedule in the Las Vegas NBA summer league Saturday.
