A bit more. I think what we need to see is two things: One, he needs to beat a big-time player at a big tournament. It doesn't have to be Novak or Rafa at a Slam, but one of Tsitsipas, Zverev Rublev, Medvedev, or Thiem at a Master's. Two, he needs to win a final - it doesn't matter what level, any will do.
Remember when he used to own Tsitsipas? He's now lost four in a row. Last year he lost once each to Tsitsipas, Zverev, Rublev, and Thiem the only times he faced them. As far as I can tell, the highest ranked players he's beaten are Denis Shapovalov, who was #12 at the time, and Bautista Agut, who was #13 at the time.
Actually, he seems to be in a similar category as Shapovalov: a talented young guy who hasn't quite put together his prodigious talents and is thus on the outside looking in of the "Next Gen inner circle." Shapo has only made two finals, though, winning one (Krajinovic at the 2019 Stockholm Open). I think FAA's seven finals speaks to his greater talent, but 0-7 is just...brutal.
If and when we see FAA do those two things--beat a big-time player (top 10, at least) in a big title AND win a title, then we might see a leap forward. If those two things happen, it might come together for him very quickly. But until it happens, well, we'll be left wondering What Could Be. Just as Shapo could be seen as this era's Dolgopolov (or maybe Monfils), so too might FAA be in danger of being the new Dimitrov. But we're not there...yet.
