Positions matter and they don’t. Catching is a speciality. Being a quality catcher makes for easier recruiting. After catcher it’s middle of the field players (they have the speed and quickness) and corner field players (they might lack the speed but mash more). A middle of the field player might get moved anywhere. They’re typically the most athletic.
If a kid gets pigeonholed as a first baseman he better fit the physical characteristics and be able to absolutely mash. Some programs don’t recruit first baseman unless they’re absolute mashers. First base and DH is where the extra players who can hit get placed.
A friend’s son was an All American at short and a first round pick after junior year at a highly ranked program. The shortstop he was supposed to follow returned for senior year. The recruited shortstop played first freshman year. While he wasn’t smooth he had the hands for it.
