There are actually quite a few HS catchers who are doing quite well as true-freshmen (HS 2020's) this season. Of course the season is just starting so only time will tell. But for ACC and SEC coaches to trust a true-freshman this early in the season says something.
Most of these kids would have been drafted in a normal year so they would never have made it to campus. Doesn't mean they will succeed in pro ball but that's true for any player!
