Despite his poor performance at Hopman Cup, Tiafoe mentioned that having the benefit of watching Roger Federer and Serena "work", how they go about their play, their attitude toward competing, etc. really informed him on how champions approach situations. I think that, if these younger guys are smart, they will learn as much as they can and even figure out a way to beat these guys while they're still competing. Roger did it with Sampras, Agassi, etc. as did Nadal with Federer and Djokovic with both Nadal and Federer.
Players who achieve 'the hard way' by beating the greats are more likely to have a more resilient game and perhaps have the "stuff" to build some type of sports legacy if they have to compete and learn to beat the best, rather than win because there is no one left.
I like Tiafoe's attitude (yes, despite the unorthodox FH). He considers it a challenge and he seems eager to tackle it.
The women's final does look like it has the makings of a competitive match, which is a good thing. I consider myself one of the early observers of Osaka's game because I remember when she was coached by her father.
Still, I'm gonna have to catch that match with her and Kvitova on the replay because I am not getting up at 3: 30 in the morning!
