Fandom is funny thing. I am a college sports guy (primarily football but have been watching basketball about the last 5 years) and I sometimes just "adopt" a team/s to follow beyond my alma mater.
I started checking out UConn in 2013.
Random circumstances...Maybe I get to know a team from their board and a community of posters..or, like WVU, who I have followed for 37 years, thru a personal connection.
We went to a bowl game against WVU in 1982..sat next to a young Mountaineer couple...we ended up going out together after the game and exchanged phone numbers with the obligatory "if you are ever coming our way".
Well...they actually did, we took them sailing, put them up...we both had a boy within months of each other and have shared many vacations as they grew up. The boys are like cousins.
I follow Auburn because my uncle, brother, sister's boy, and cousin are Auburn grads.
