The days of UF being the clearcut top law school in Florida are over, people who continue to say so are a few years out of date. FSU is strongest in the north and has the best employment numbers (boosted by Gov't jobs in Tallahassee). UF has the most portability of the three schools, but their Employment Score actually dropped below Miami's and FSU's this year. However, they still have the top BigLaw score in the state. Although Miami's score is inflated by school funded jobs (PI placements), it still places quite a few more students in real legal jobs than any other school in the state (it has VERY large classes). As such, a top 10% finish at UF might grant you a BigLaw spot in Miami, but any other kind of rank will make it very difficult to make your way down to Miami. The schools are 5 hours apart (Gainesville is as close to Atlanta as it is to Miami..). UMiami is the best option if you want to practice law in Miami, outside a T20 (Vandy, Duke, Havard, Yale, etc).
Miami's employment numbers aren't fantastic, if you're aren't top half then you need to drop out, not just because you'll lose your scholarship, but without connections you don't stand a viable chance of landing a job. In general, Florida is a tough market, but one that is improving. I know there are a few people on TLS who like to say that law school is vocational school and not vacation school, but don't go to BC if you want to live in Florida. Give up your career before you give up your home.
In conclusion, if you want to be a lawyer in Miami:
1. Go to Vandy/Harvard/etc and fight your way back south
2. Go to Miami and finish in the top 1/3 of your class
3. Go to UF and finish in the top 10% of your class
