this is a difficult question for me to answer, but interesting nonetheless. to be in your position is admirable, it seems that every sport out there I have the teams I follow, I have followed for a while and it's too hard to change by the time you have a little history with your team.
I have always pulled for the Pittsburgh Penguins. they have a winning history with guys like Jaromir Jagr behind them, and a flashy new offensive sensation in Syndey Crosby.
they are squaring off against the Detroit Red Wings in the Stanley Cup (the Finals), this year for the second year in a row. Detroit, like always, is heavily favored. Detroit is your perpetual winning team in the NHL, kinda like the New York Yankees of hockey.
plus, Pittsburgh's mascot is the best. for hockey, who or what can beat a penguin?!
