Also, if they did construct a new stadium I would think the highways and roads around the stadium would also undergo a makeover to accommodate expected traffic.

Either way, in my opinion every baseball team should have its own stadium.

Not sure if you’ve ever watched a game there – but even in the playoffs the Marlins rarely reach 66k, except in the World Series. They’ve had NLCS/NLDS games where they had 40,000 or so in the stadium (leaving about 25,000 available seats!!!).

Given their fans, I don’t see the larger crowds in Florida as much of an advantage and think it had to be their players not their fans that gave ‘em those playoff victories.
