im a huge dolphins fan and have been for many years, but being british i dont watch a huge amount of other north american sports as they are fairly hard to access in england. Im always interested in which city in america has the best legacy in sports, i guess miami does alright with the fins and the heat but as much as i hate the patriots. boston has a great history with the celtics, patriots and bruins. Are there many other citys with several successful franchises to rival boston?
