One thing I've noticed about this region of the country is how huge NFL football is. In Florida, college football rules. Alumni groups for Florida State, Florida, and Miami were all over the place, and the games are a large part of the state's consciousness.
Here, pro ball dominates. On Fridays, it is common to see a few coworkers wearing team jerseys. Badge lanyards proclaiming various allegiances are popular as well, as are various methods of decorating your cubicle.
The popular teams are the Washington Redskins, Baltimore Ravens, and then everyone else including the Pittsburgh Steelers and Dallas Cowboys. I tend to adopt the local team after a while, so I'll pay attention to the Ravens and Redskins.
