If you look at rosters for mid D1 and D2 programs ( especially here in Florida) JUCO players fill rosters.
One thing to remember is that many JUCO players normally arent recruited unless they have the credits to transfer which takes about 4 semesters.
One other thing, and frustrating at times, many are recruited but don't actually decide until the April signing period where to play. They attend big JUCO tournies ( big one in Auburndale) in hopes of catching a D1coaches attention, with sites on the larger programs when in need of losing to the draft, especially when the lose players to the draft unexpectedly.
Now here is a story. Last year son while at FSC (D2) was recruiting a pitcher who decided on FAU (D1 over D2). Ironically, son was hired as the pitching coach at FAU and the player he wanted is the closer.
Baseball is a small world, especially here in Florida.
BTW, FAU play the Charlotte 49ers this weekend who have 6 or 7 JUCO transfers on their roster.
