You're arguing two different things. You're dismissing that Rafa came close to Roger in 2007, given Roger's prowess on grass, and calling it a bad match-up. That was Rafa at 21 and Roger at 25. Roger with 8 Wimbledon titles, in the end. Then you say, with no transition, that Alcaraz has already beaten Novak twice at W, but that's when Alcaraz was 20 and 21, and Novak 36 and 37. How is that comparable?
Look, I know you're making a leap to compare Charlie with Rafa in fantasy tennis, but I think you have to try harder to compare apples to apples. You may say that Alcaraz has a game that more suits grass than Rafa's, but Rafa has proven himself on grass, against the greatest grass courter in the men's game. He also wanted to win at Wimbledon more than anything, so you can't just say that Alcaraz loves it more.
Also, did you just say that Alcaraz is better on grass than Roger?
