I couldn't tell you how many were former blue chip prospects, but that wasn't my point to begin with. My point was that JUCO's who commit to the Huskies in the fall or early winter do not seem to show up at UConn the following spring, but rather for the following fall ball season.
I do recall since I started following UConn baseball recruiting that at least one JUCO that had committed to UConn ended up getting picked in the MLB draft, and ended up going pro instead of reporting to Storrs that fall. I do not remember the name of that player. We will see if it happens again.
