2018/2019 version of Rafa was still very good. Not as great as the 2010 peak version, but Rafa's body was still functional enough to handle the rigors of a full schedule, and be competitive. Much better than any version post-French Open 2021, when Rafa's body was broken. I could see it at the Citi Open (just compare his performances at that tournament to the one he had against Sinner at the French Open 2 months earlier... it was night and day). Rafa caught lightning in a bottle in early 2022, and was really lucky to win the French Open (he really should have lost that match to FAA). Rafa's level of play in early 2022, with a broken body, was just not sustainable throughout the entire course of a season. He really needed to take a break after the FO, to heal his body from everything IW onwards. Playing Wimbledon was a mistake, and quite frankly, it cost him a chance at the 23rd slam at the US Open.
