Zach LaVine jumps really high and talks really fast. He exudes a brash confidence like Russell Westbrook and plays with a chip on his shoulder the size of Bill Walton.

This latest UCLA product is headed either for a stunning rookie season with the Minnesota Timberwolves or cold, hard NBA reality.

“I’m a very confident person, I always hold myself to high standards,” LaVine said Friday after scoring 22 points with four assists in the Wolves’ sixth and final Summer League game. “You know, there’s a lot of doubters on me. I feel always like changing peoples’ minds, you know, ‘He’s not NBA-ready, why’d he come out?’ and different things like that. So I just come out here and always try to prove my point. I think I fared well for myself.”

There was little not to like about the 6-foot-5, 19-year-old’s debut in the Las Vegas Summer League. Everybody was aware of his athleticism coming in, but many were skeptical about his decision-making and the durability of his 180-pound frame..

“I definitely have to get in the weight room and let my body mature. But if they can’t touch you, you know, strength really isn’t a factor,” LaVine said. “I feel I’m a pretty physical person, just not the strongest yet, so I definitely have to get into the weight room. But I use my speed to my advantage.”

He averaged 15.7 points a game and more than five free-throw attempts per game in the Summer league. Twice he got to the line 10 times.

Fans mostly will remember a dazzling array of dunks. He’s already nominated himself for the dunk contest when February’s All-Star weekend props up its big tent in New York City.

“I’m definitely going to be in the dunk contest, know that,” LaVine said “I haven’t lost a dunk contest for a long time, maybe since I first started dunking. So I have some dunks in my package.”

The Wolves are more intrigued by the 13th overall pick’s size at the shooting-guard position, his ball-handling and his higher-than-expected court IQ at point guard. He bounced between the two positions during Summer League.
