Sacramento Kings point guard De’Aaron Fox shocked his Team USA counterparts during his brief participation with USA Basketball before he withdrew from the team. The 21-year-old did, however, leave a lasting impression as one of the fastest players to take the court.

Fellow USA teammates Kemba Walker and Donovan Mitchell were among the first to take notice:

“No question, he’s No. 1,” said Walker, according to Jason Jones of The Athletic. “He’s fast. He’s fast. He’s super fast.”

At 6-foot-5 and only 183 pounds, Fox is able to blur past his opponents, possessing end-to-end speed like few others do in a league characterized for its sheer athleticism.

Mitchell, who is faster than the average man at his position at only 6-foot-3, concurs that Fox is easily the fastest player in the league:

“He’s easily the fastest in the NBA in my opinion, as well as being under control,” said Mitchell. “It’s one thing to be fast and out of control but he’s fast and under control. He knows what he’s doing and he knows how to get to his spots.”

Fox argues that while many of his colleagues told him he’d gotten faster than this past season, it wasn’t that he worked on his speed, but rather his body overall that helped him reach new athletic peaks:

“I don’t mess with the track, that s**t hurts,” Fox said last week. “I applaud people who run on the track, but that stuff hurts my legs, I can’t do it. But as far as speed work and agility, I don’t work on it. It’s kind of natural. When people say I’ve gotten faster, it’s really when I started getting stronger, I started to get faster. But I never necessarily worked on the speed aspect.”

De’Aaron Fox will enter the 2019-20 season primed to break out as a potential star in the league, having already made a sizable jump from his rookie season. Kemba Walker and Donovan Mitchell are certainly expecting it after seeing him up close.
