With the exception of the Thursday night game, every single Dolphins game this year is scheduled for 1pm on Sunday.
Which sucks because right now, with the exception of the Monday night game in Week 3, every single Buccaneers game is scheduled for 1pm Sunday.
So basically, barring either the Bucs or Dolphins games getting optioned into Sunday Night or 4pm start times, it looks like if you're in the Tampa/St. Pete area you are only going to get a chance to see 3 of 13 games broadcast on regular broadcast TV. They would be Week 3 (home vs Oakland), Week 5 (at Cincinnati), and Week 8 (Thursday Night Football at Houston).
You'll have to find a bar that you like. As I said, there are no shortage of bars in the area that have lots of TVs and The Ticket. It's almost become like the standard setup. But you might consider going to a few of them, making sure you like the TV sizes and angles, maybe asking the people who work there if they generally get a lot of people to watch Dolphins games (which would mean more prominent TVs, maybe sound).
