We don't seem to be recruiting the JUCOs the way we once did. Even back in the '80's and after many I spoke to talked about the risk of relying too much on JUCOS. Often, they were kids we couldn't take academically coming out of HS. Still, doing it right, we got some of our best players ever out of the JUCO ranks: Cortez Kennedy, Fast Eddie Brown, Shockey, and others.
I can't quite figure out why JUCO recruiting has fallen out of favor, except for the fact we can fill immediate needs more easily from portal transfers.
