Check out Rollins College, in Winter Park, Florida. They are DII playing in the Sunshine State Conference that includes Unversity of Tampa and Florida Southern, two national powers. Rollins seems to have a lot of NE players. It's very expensive, though, and I'm not sure of the level of support baseball receives from the College in terms of entrance and so forth. It's very selective.
Also, I believe Eckerd College in St. Petersburg has a lot of NE guys. Very small campus, beautiful location on the south end of St. Pete Beach, great marine biology program, Sunshine State Conference, too. Eckerd is a cut below Rollins academically and in cost. Better location, too, on the beach and near Tampa, St. Pete, Clearwater, Bradenton, and Anna Maria Island.
Check out Barry University in Miami, too, and perhaps Lynn University in, I believe, Boca. Same deals.
