this happens mostly with friends more than family...since most of my family is from New York, we all like the Knicks, Rangers and Mets (not the Yankees, none of us like the Yankees)...no one likes the Jets but they all do like the Giants, meanwhile, I like the Bills. My stepdad loves all Detroit teams, Lions, Red Wings, Pistons, Tigers, Wolverines (but not Mich St.). Father-in-law likes the Yankees, Packers, Huskers (good lord does he love the Huskers!) but isn't really big on the NBA or NHL (though we go to college hockey games and Creighton basketball games all the time). However, he's just a huge sports nut in general so he pretty much likes everything.
