Anyhow, I will say this about Rafa. If there is anyone who can comeback in this scenario and win another Slam, it would be him. So I wouldn't completely give up hope. To be honest, if he makes one more run at RG next year, I'll be cheering him on next to you.
So while I agree with you that it is very unlikely that he returns to his former self, even the great-but-not-as-great 2017-22 version, as far as the whole tour is concerned, I wouldn't be surprised to see him be a real factor on clay next year and, if he's willing to consider the other tournaments as warm ups and play a limited schedule, be a real contender for RG. And who knows, maybe he'll do a Pete and go out hoisting the trophy. I'd love to see that.
