The comparison to football and baseball does not hold. Football has 8 home games, almost always on Sunday afternoons. Baseball has 81. It is quite easy to fill a football stadium 8 times a year, yet the Dolphins do not do that. We just bought 8 tickets for opening game from the Dolphins themselves. I've been to 3 games there, none of which were close to full. They definitely have trouble filling it. A big part of the problem is it is in the boonies. There is nothing for miles surrounding it. That means everybody has to drive. Almost all great attended baseball stadiums are located in relatively easy reach of public transport, if not just a downtown area in general. It is very difficult to get 30,000 people to drive to a giant parking lot 13-14 times per month. Twice a month on a Sunday afternoon over a four month period, not hard. 81 times during the hottest time of the year in one of the most oppressively hot places in America, very difficult. And of course, as others noted, the Dolphins play from September through December, not in June, July and August.
