How much time do you give him?
The city of Miami gave him a lot longer of a leash than I ever would. I give him two years though. If, and this is a big if, they win the WS in the next year or two and the Hispanic community there gets won over it'll work. If not, it'll be back to empty city in no time.
Lots of competition for attention and dollars in Miami, though.
The biggest problem is that, unlike with NYC, Chicago, or DC, the weather there is nice year round so it's not just NHL vs. NFL vs. NBA vs. MLB, it's all of that vs. partying, boating, beach...etc.
