John McEnroe reflected on the reasons why the United States have not been having a Grand Slam winner since the 2003 US Open with Andy Roddick. McEnroe said: "Now, we have good athletes. It’s that the cream of the crop, you look at Djokovic, Nadal, Federer, Murray, these people that are some of the best athletes their country has produced.
We have Tiafoe is a great athlete. He’s still learning. He made a breakthrough getting to the quarters of Australia. There’s going to be guys that are dangerous, but at the moment, the more athletes in the game because of the quickness of the game, the better chance we’ll have of making that breakthrough.
At the moment, it’s been a little bit difficult to see recently because you just — it would be so helpful for the men’s game if we had a guy that was winning, winning Slams." On Americans' chances at Wimbledon, McEnroe added: "I think that the odds are pretty low.
Isner has been out. He finally seemed to figure out how to play on grass last year, so he’s sort of an unknown quantity. And the other guys to me, whether it’s Opelka, he’s like a younger version, Tiafoe has been struggling.
There’s been some injuries. Fritz is solid, but he doesn’t look to me like there’s guys ready to go and make that move or they would make that deep run. I think that in a couple years you’ll see some guys that will be in the top 10, but I think anyone that we talk about right now would be people that need to add more to their game and some seasoning and that belief that is obviously critical to sort of make that jump into winning Slams."
