And besides, there's more in this than simply a new ballpark for the Marlins. There's going to be a whole lot of stuff springing up around the new park. Could Miami really afford the alternative to getting a new stadium, which would have been losing the Marlins altogether? Somehow I doubt it.
The city of Miami is
projecting a 100 million deficit for 2011. Interestingly enough, the cost of the parking garage for the new stadium is $100M - to be financed through a bond issue, so it's not a 1:1 relationship: Kill the stadium, the city balances its books, but the increased debt level means more debt service.....
In the current economic reality, commercial credit is still tight, consumer spending low, and overall confidence is low. Will a lot of new development "spring up" like flowers after a rain around a new stadium?
Since the majority of visitors to the stadium are local, how much increased spending in the area take away from spending in other areas?
New stadiums aren't about increasing the bottom lines of the localities they're in, they're about increasing the organization/owner's bottom line with more suites, PSLs, renegotiated concessions deals that are more favorable to the organization, tax credits and breaks for building, pieces of the parking revenue, and so on.
^Since no one goes in the first place, it hardly matters. Florida gets better spring training crowds than it does for their MLB teams.
^ I still think the Marlins attendance will go up when they get the new stadium. I'm convinced that part of the reason they don't get many big crowds now is that Sun Life Stadium simply sucks. You get a stadium that sucks, your crowds will suck. The new stadium will look better, play baseball better, and have a fucking ROOF, all of which can be nothing but a good thing.
The product on the field sucks. Having a new barn won't change that and the novelty of going to a brand new stadium will last 1 game? "Yep, new stadium's cool, team still sucks". Most sports fans aren't going to shell out hundreds of dollars on a consistent basis to see games in a new stadium unless the team is a good draw.
Detroit's Joe Louis arena is probably recognized as one of the worst arenas in the NHL, yet the Red Wings are one of the top draws in the league year over year. Why? Because the Red Wings have made the playoffs something like 19 years running.
