Former NBA champion Ron Harper believes Luka Doncic is showing a huge difference from his time with the Dallas Mavericks and the LA Lakers.

Luka Doncic is a man on a mission this offseason. The former All-Star has been putting in the work, and the results are staggering.

Doncic’s body transformation has Lakers fans celebrating, as the point guard looks to be in the best shape of his career.

Even Dallas Mavericks fans are shocked by Doncic’s weight loss. It’s clear that Luka is trying to clean up his act heading into the new season.

However, not everyone is as impressed. Stephen A. Smith demanded consistency from Doncic when it comes to his shape.

But one former NBA star had some interesting thoughts about Luka Doncic’s weight loss. In fact, he thinks it’s an indication of the star’s mindset.

Former NBA champion Ron Harper took to X to weigh in on Luka Doncic’s recent body transformation.

He believes that Luka Doncic’s lack of effort and body shape during his time with the Dallas Mavericks was a sign. Harper added that Doncic got too comfortable in Dallas.

“You saw Luka’s body and non-workouts in Dallas, so you can make your own opinion. He got comfortable in Dallas.”

Doncic always spent his offseasons getting into good shape. But by the middle of the season, he would let himself go.

Luka was never grotesquely out of shape, as some hyperbolic commentators might suggest. But his conditioning was always a point of contention.

LA Lakers set to benefit from a motivated Luka Doncic

What may have been the Dallas Mavericks’ headache could now become the LA Lakers’ blessing. After an acrimonious trade to the Lakers, Doncic is motivated to prove his detractors wrong.

Tony Allen believes Doncic’s new physique makes him scarier. With a smaller frame, he could even show major improvement as a defender.

Even Magic Johnson applauded Doncic for the hard work he has put in. Now, the Lakers are looking forward to reaping the rewards of a motivated Luka Doncic.

If he takes the same mindset into the regular NBA season, then the Lakers might be the most dominant team in the league.

Keep a close eye on Doncic heading into the 2025-26 NBA season, as he looks to show the Mavericks why they made a mistake trading him.
