Not a big deal. everyone is different. We are raised differently, we raise differently. I do know that for recruits they pick coaches, programs and schools for so many reasons and by that time they have been exposed to so many teams and programs. They have traveled all over, seen other places and have actually cheered for other teams and programs.
To each their own....
I think a big difference is if people are more lovers of the game or more supporters of their home area.
The average person wearing a Gopher sweatshirt isn't so much watching the zone blocking schemes, cycling the puck or waiting for a back post screen. They are watching their home team do well and trying to beat the rival teams. People watch the Olympics and root for the USA in badminton, diving or curling even if they know nothing about the coaching or even the rules of the sport.
But some true lovers of the sport concentrate more on the details of how it is played more than who is playing. If you are going to be a great player, you had better be a true lover of the game.
And of course, many fans are a combination of both homers and an aficionado of the sport.
