I'd have to see the replay, but at the point they legit started fighting each other for control of the ball I remember Gobert having two hands on it at about his shoulder height and Ingles having one hand on it. Gobert then started to raise the ball and Ingles more or less used his one hand on the ball to dislodge Gobert's grip on it to the point that Gobert fumbled the ball, lost balance and couldn't stop himself from throwing the ball out of bounds as he tried not to fall over.
I'm glad they both went for it, but at the point that it became a struggle I feel like Ingles was the one who should have let go.
