It’s so much easier now to watch an out-of-town team than it used to be.  With the proliferation of sports television packages, numerous NYC bars now cater to fans of another city’s sports teams or a specific out-of-town professional or college team.  One site that I’ve used recently to find out-of-town friendly sports bars is http://barhappy.com/new-york-city, which gives you the ability to filter your bar search by specific sports teams.
