I'm not even sure how this is a question. Zach Lavine is having a much better year than Dante. I'm glad we have Dante. I think he could be REALLY good in a couple years. But Lavine is clearly better right now. In essentially the same minutes per game, Lavine is averaging more points, assists, and rebounds. He also has much higher shooting percentages. Dante is certainly a better defender right now, but he's sort of an anomaly. Not many 19-20 year olds are expected to be good defenders right away. Lavine has much more confidence right now. I'm hoping an off-season of working on physique and developing a left hand will give Dante some confidence.
Who's going to be better in 5 years? Who knows? Let's hope it's Dante.
The biggest think Dante has going for him is that he hasn't played against much competition during his life. Zach had the benefit of playing US High School ball and UCLA. Dante went straight from Australian HS Ball to the NBA. Next year will be much more telling than this one regarding who will be a better player.
