The success of the UF back to back NCAA Championship teams (2005-07) was mostly built on out of state players. Taurean Green from Lauderdale was a very key guy to be sure; and Chris Richard from Lakeland was a nice big off the bench. That's two players! The rest, including the key guy, Joakim Noah from NY/NJ, were all from OOS, iirc. I think that trend has continued and the Castleton kid from Deland was the ONLY Fla HS recruit on their roster last season.
Coach Ham has really, IMO, been a global recruiter at FSU. A lot of bigs from Africa, a lot of top-tier JuCos from all over the country and, yes, some very good Florida players. I couldn't say though that it appears he particularly targets guys from Fla high schools, other than the obvious super talents like Scottie, who everyone tried to recruit. He'll take them from anywhere.
Think I did some research a few years back that covered recruiting of Fla HS players by UF, FSU and UM. Surprisingly, we hadn't done THAT much poorer in-state, over the last 20 years or so, than the two schools up north. Think I also found Coach L held his own with Ham, Perry and Frank in getting Florida HS players. No real drop off, if any.
