And what percentage are THOSE players of everyone who has ever had TJS? probably not even .01% that's not a relevant sample size. It also said the success rate goes DOWN after 35. How many guys on that list are over 35? Also some people are just built differently, the fact that you can list 5 guys from the thousands of people who have successful TJS probably does more to make my point than yours.
Look, anything can happen, his arm can come back STRONGER, WEAKER, or the Same. Odds are he will be where he was before he got injured, which was about average. If you want to believe otherwise then I say you're just being a pessimist, which is well within your right and a common theme on this board.
I expect and hope his arm strength is fine for SS, and I hope the team gets a stopgap in 2024 and puts him back to 2nd too. If he's healthy, I think he will be fine there. He lost arm strength BECAUSE he was injured, it's perfectly reasonable to assume he's fine if recovered. It's ok....it won't hurt to be a little optimistic and think he will be in the majority of people who recover.
