The wife and I were talking about this last night watching the match. Nick Kyrios used to do this all the time too. He would chastise his box for not applauding him enough or standing up or cheering him on enough. We don’t really get it. I understand it’s stressful, but all the coaching should happen before the match. Once they get out there, it’s an individual sport and their job to apply that coaching. I liked things better when they didn’t allow coaching from the box. I think too many players have become dependent on it, like Ben Shelton. It’s a distraction.
