In May, reported The Telegraph, "the US Open put forward plans to experiment with coaching from the stands—in which players can ask for advice between points as many times as they want—in main-draw matches at Flushing Meadows."

The new rule was approved by the Grand Slam board in Paris. But the news did not go over well with many fans and players. 

"I don‘t support on court coaching," Roger Federer said. "I think that I have the best team in the world, and so I don‘t think it‘s fair that I could profit from that and another guy, who has maybe no coach can‘t benefit at all."

The ITF currently allows on-court coaching at their junior events, and the US Open and Australian Open have tried the new rules in qualifying rounds since 2017. The WTA has had on-court coaching in place at non-Slam events since 2008.

Adding coaching in the main draw seems like the logical next step, but with the recent backlash from many sports commentators, players and fans, the US Open put a pin in the plan, while the Australian Open may try it in January

What do you think: Is it time to replace tradition with a change this big?
