Coco Gauff's former coach, Brad Gilbert, had quite the reaction to the latest no-travel call against Milwaukee Bucks star Giannis Antetokounmpo in Tuesday's 121-111 win against the New York Knicks.In the first quarter, Giannis took multiple steps (almost 5 to 6) after gathering the ball on the fast break, and the referees did not call a travel violation. As per NBA rules, players are only allowed to take two steps without bouncing after gathering the ball. Thanks to the potential ignorance of the NBA referee, the Bucks forward was able to get inside the paint and make a well-contested shot.The clip of the same is going viral on the internet, and even Gilbert can't help but laugh at the no-travel call.
