Are you comparing her with Becker and Rooney, both superstars and one of the best of their generation in what they did?
I think Raducanu is a great talent who will soon enough be top 10 if she continues like this but that she is also being helped by a weak women's field where no one stands out and where you can beat everyone when you're on your day. If she was doing this twenty years ago and was beating Williams, Clijsters, Henin, Davenport, Mauresmo, ... on her way to GS semis and finals aged 18 I'd think she was headed for a Serena Williams-like career.
It's not that long ago when Osaka was winning Grand Slams aged 21-22 and we thought she was on her way to dominating female tennis.
