<p>Some DI schools have junior varsities, but I believe that JV players rarely if ever end up on the varsity. Most varsity teams have a very small numbers of walk-ons who sometimes earn scholarships by their senior years as a reward for their hard work in practice. Some lower level DI schools also have recruited walk-ons, who come either a) with the expectation that they will get a scholarship in their sophomore year or b) compete with other recruited walk-ons for such scholarships.</p>
