Mostly boring with one interesting one:
Grew up in Buffalo, so Bills and Sabres
Went to Penn State, so the Nittany Lions
Travel soccer team growing up was the Arsenal, so root for them.
The UNC basketball fandom started in HS. I have a brother a year younger than me and we were pretty competitve. My freshman year, his 8th grade year, our Varsity High team played against a team from downtown Buffalo so we went to watch the game. The Buffalo team crushed us and one player was really good. My brother said "I'm going to find out where that guy is going to college and start rooting for them". We saw in the paper the next day (yes, I'm old) that he was going to Duke. So my brother started rooting for Duke and since I am a good brother, I started rooting for UNC. We had tons of fun through HS, college and post college going back and forth during those awesome rivalry games.
Who was the player that went to Duke?
Laettner
That's a great story!
And now I know we are probably the same age +/- a year or 2.
My HS is lilly white with zero basketball stars but full of famous athletes in other sports...Clayton Kershaw, Matthew Stafford, Scottie Scheffler to name a few.
However, in 1989, our basketball team was legit. Went to the playoffs and faced a team from Lancaster High with a fella named Thomas Hill on the roster. They were supposed to beat the brakes off our team, but in dramatic fashion, the HP Scots won. Thomas Hill went on to star at Duke with Laetner but for one night in Dallas, the glory belonged to the Scots.
