How much benefit do smaller schools gain from getting more younger kids on Varsity than larger schools, especially those with successful programs where the competition for Varsity spots are intense?

Does the additional Varsity experience at smaller schools over their High School careers give them an edge compared to wrestlers who remain on JV until their Junior or Senior years before making varsity in a large program?

Or, does the abundance of quality partners for practice in a large program make up for that lack of Varsity experience?

Personally, I think coaches want both Varsity experience AND a variety of quality practice partners available for each wrestler. But, that's difficult to attain. If a school is short on numbers, they are more limited in practices. If a school has lots of wrestlers, they have problems getting JV wrestlers enough early Varsity experience (how many schools host a major Varsity tournament and want JV teams to participate?).
