Gilbert Arenas Reveals Biggest Concern About Victor Wembanyama

Gilbert Arenas is believing the hype around future NBA star Victor Wembanyama ... telling TMZ Sports the French hooper is a "generational game-changer" ... but there's one thing that could keep him from his full potential -- his feet.

We spoke with Agent Zero about the most hyped prospect since LeBron James, and he says if the 19-year-old possesses the basketball I.Q. like fellow international stars Nikola Jokic, Giannis Antetokounmpo, and Luka Dončić ... he will thrive in the league.

But while Gilbert says Wembanyama checks off so many boxes, the one thing that concerns him is the 7'2" giant's dogs ... admitting foot issues could potentially impact his promising NBA career.

"That's the only thing I think will slow him down is [his] feet," Arenas said. "Other than that, as long as he's healthy, I don't see anyone stopping the progression in his dominance."

While Wemby has had a number of injuries in his short career, he hasn't had any foot ailments as of yet. But unfortunately for big men, foot injuries have historically been a pain in the ass -- just ask Yao Ming, Joel Embiid, Zydrunas Ilgauskas and Chet Holmgren to name a few.

Aside from Wemby's feet, Gil isn't worried that Victor's thin frame will affect him in the pros ... explaining he's been playing against people stronger than him his whole life and turned out fine.

The Spurs won the NBA Draft Lottery ... meaning they can select Wembanyama with the first pick in June -- and it sounds like Arenas thinks San Antonio will be getting a future all-time great if they take Victor.
