You can have a good run with things going your way. It happens most of the time, in fact.
Most champions need some degree of luck, unless of course you're Nadal at Roland-Garros or Sampras/Federer at Wimbledon.
Regarding the bolded section, I say both. I don't have to adhere to your dichotomy. It's a good run that isn't as impressive as it could be (like many other runs).
Does that change anything on paper? Not at all.
Does Seles being injured change anything
on paper in terms of Graf's achievements? Not at all. Would Graf's accomplishments have been even more impressive if she'd had Seles as a full-time rival and still managed to concoct a career like hers? Absolutely.
Saying "freaking Vesnina" and in the same breath talking about "amazing Barty" - because one is a fellow countrywoman and the other isn't, because one is younger than the other and seems to "promise" more - is perfectly understandable, as I mentioned before, but only if you have a certain bias. A bias that I think is understandable, I'm not disputing the fact that bias is an integral part of sports and fandom. I don't see a problem there at all.
However, as I'm sure Aussie_Darcy doesn't want to be misapprehended as an overreacting Orville (I just made this one up), I sure as hell don't want to be misconstrued as the opposite, a "buzzkill", just because my approach in these matters is on the cautious side. I wouldn't be quite ready yet to say "Barty is the next GOAT" (

What you see as "passive-aggressive" behaviour might just be the expression of doubt or ambiguity. Something that is very rarely expressed when people are engaged in debate.
