Mercer CC, Rowan Gloucester, and Cumberland CC are all programs competing for a national championship every year in baseball. They're good, with plenty of P5 4-2-4 guys, and some pro guys depending on the year. If I'm correct, Rowan beat Cumberland in the national championship game last year.
I think going back as a college student and playing HS baseball would be pretty pathetic. IMO it's much much different from a post grad year. How wild would it be if you took this route and got cut from the HS varsity team
