Giannis Antetokounmpo has faced dozens of all-time great players in his 13 seasons in the NBA, so when he shares his opinions on who are the hardest to play against, you know it's coming from an informed place. 

That's why Antetokounmpo's endorsement of Kevin Durant holds so much weight.

While filming a commercial with Dwayne "The Rock" Johnson to promote Johnson's upcoming Disney film "Moana" a behind-the-scenes clip of the Milwaukee Bucks star and the wrestler-turned-actor chatting about basketball, with Johnson asking Antetokounmpo about some of the best players he's faced in his career. 

Antetokounmpo praised several players, including Victor Wembanyama and LeBron James, but when Johnson asked who the toughest player that Antetokounmpo has ever guarded was, there was only one answer in the Greek Freak's mind. 

“Toughest player gotta be KD," Antetokounmpo said. "Great talent. Probably the best scorer of all time.”

Antetokounmpo kept his explanation short and sweet, keeping his praise of Durant to his overall talent and scoring ability when Johnson questioned him on the specifics of what made Durant so tough to play against.

He has good reason to feel that way about Durant too considering their history of playing against each other. 

The Durant-led Brooklyn Nets were the team that came the closest to interrupting what's been the only championship of Antetokounmpo's career at this point.

During that 2021 postseason that ultimately culminated in Antetokounmpo and the Bucks landing on top, they faced Durant's Nets in the Eastern Conference Semifinals. 

Brooklyn was the only team that forced Milwaukee into seven games that postseason and they almost beat the Bucks too, leading to the now iconic "toe on the line" moment in Durant's career.

In Game 7, Durant hit a long two-point shot to tie the game at 109 and the only reason that it wasn't a three-point game winner was because Durant's toe was on the line of the arc, demoting it to a standard field goal.

The Bucks took that game in overtime and went through the rest of the playoffs with relative ease, but it's clear that moment, along with the rest of Durant's storied career, has stuck with Antetokounmpo. 

Antetokounmpo's praise of Durant also takes an interesting angle considering the trade rumors around Antetokounmpo this offseason. He very well may be on a different team by the start of next season and the Rockets could be an interesting suitor for the star. 

His praise of Durant is more likely than not just simple in the moment praise of an all-time great, but the possibility of the two standout forwards uniting in Houston isn't off the table either.
