The suggestion that a Kid wait until they play Varsity to reach out to colleges is ridiculous. Varsity where? Some of the kids from this message board would be the greatest ballplayer, as a freshman, in the history of many schools in Wisconsin whereas might not start varsity until an upperclassman in a Baseball hotbed.
Even in my son's conference, in some high schools any functional athlete who could run a 8 flat 60 could start Varsity as a freshman, however at the Top 2 programs you better be a D1 prospect to have a shot at starting. It is all over the place.
