I’m in the air heading to my youngest’s college games so late to reply.
My oldest was very young for his grade and did a PG year because of his immaturity. It didn’t help, but that’s another story.
I agree with Two Boys.
The PG year, IMHO, is for reasons other than jockeying for a better baseball recruiting spot, e.g., maturity/age, illness/injury, grades and test scores, etc.
