No, I will not go root for those teams, I am a Dolphins fan. Always have been, always will be. I am not OK with "mediocrity", but I am also not OK with bandwagon negative fans. I don't live in Florida, so I can't go to every home game, but being out of state allows me to see what is going on elsewhere in NFL cities and I can see a big problem with the Dolphin fan base.
My first Dolphins game in Miami was the 2000 playoff game against the Colts. I just happened to be in Florida(Orlando) the week they were up in New England and the weekend after. After the Dolphins won the division title I thought it would be really cool to drive down to Miami and see the playoff game. Though I thought tickets would be impossible to get. Called up, and I had a wide variety of tickets to choose from. Not only that, the game ended up being blacked out in Miami because they didn't sell out the stadium.
Since that season, I make a special trip down from Pennsylvania to see the Dolphins play in Miami. It is a shame to say, but every time the stadium is far from being filled and a lot of the fans at the game are not even Dolphins fans. Last year I was at the Bears game and the year before that the Saints game. Both games had a fair share of empty seats and I would say the stadium had close to 40% Saints and Bears fans. It was really pathetic last year because the game against the Bears was a prime time night game when the Dolphins were in the thick of the playoff race. Thousands of empty seats and Bears fans everywhere. I thought I was in Chicago when I went to my seat.
Everyone talks about how this team needs a new QB, or new coach, or new GM or new owner. Maybe we need an upgrade to the fan base also? I know some of you don't want to here this, but this is a big problem and became a national laughingstock with the whole "We want Orton" chant at the FREE practice at Sun Life Stadium.
The other prominent excuse I get from Dolphins fan is exactly what you said. "play in cities with not much else to do". That is the oldest most pathetic excuse out there. The Dolphins play a regular season home game 8 times per year. There are 365 days in a year, so a season ticket holder would have to commit 2.2% of their year to attending the games. Is there so much to do in Miami that you can't spare 8 days(we are only talking in most cases a commitment of 4-6 hours in these days) to go to a game? If you don't fish, will the fish go away? Will the ocean go away that you can't swim the next day? Come on now.
If the Dolphins have a losing season, Sparano will be gone, Ireland might be gone and they will probably draft a first round quarterback. Everything the fans seem to be yelling for. Still though, the fans will still stay at home, the stadium will have empty seats and opponents fans will fill the stadium. That problem will never go away and is a major problem that most of you are blind to.
