Fabrication? How about delusional on your part that you have no idea how much work it takes to be a MLB catcher (neither do I, but it seems that I have a much better understanding than you). In Rutschman's 1st 3 years in the MLB, he caught 329 games, (not including DHing), you don't see even veterans catch that many games these days. (They don't because too many catchers wear down & land on the IL). For reference, many have said that Jeffers is a primary catcher. In his 6 yrs he has caught 420 games.
First of all, Rutschman caught 293 games 2022-2024, his first three years. Maximum was 110 in 2023. Get your data correct.
Second, the idea that's somehow too much is pure poppycock. Sheesh.
Cal Raleigh caught 378 over the same three years.
~120 games at catcher has traditionally been the standard for catcher #1. Roughly 3 of 4.
