I would add a team in McMurdo Station, Antarctica and they would be called the Chill, or the Freeze. The mascot would definitely be a giant ice cube, or a giant penguin. I picked this because you never have to worry about having the ice melt in the summer because it’s always COLD!
(The warm season lasts for 2.5 months, from November 22 to February 7, with an average daily high temperature above 24°F. The hottest day of the year is January 5, with an average high of 33°F and low of 25°F. The cold season lasts for 5.3 months, from April 18 to September 28, with an average daily high temperature below -1°F. The coldest day of the year is August 11, with an average low of -18°F and high of -9°F.)
Yes, the population is low, but no team in their right mind would want to go there, and whatever team does is not conditioned for the weather, so our home ice advantage would be ridiculous. Besides the fact that it is close to every time zone (since all time zones come to a point down there) it branches the league out into another location besides North America. Adding this team would be beneficial to the league because it would also add jet lag to opposing teams, so therefore whoever comes out and goes home has a rougher time in addition to the weather. I wouldn't be surprised if the team would go undefeated at home in any given season.
