You're right... Here's an example...
Growing up in NY I've always been a diehard Yankees fan... I was 7-8 years old respectively when they won the series in 77-78... That was when Reggie became Mr.October (Still the greatest sports moment of my life..lol). I got to see them win 5 more titles in 96,98,99,2000 and 2009... All big moments for me....
You know what else felt good as a baseball fan?? Seeing the Red Sox finally win one in 2004 and the Cubs win one in 2016... Two storied franchises that absorbed tons of anguish all my life..... Their teams and fanbases finally reached the top of the mountain and in reality it was good for baseball... Historical moments are always a good thing so yea , I can appreciate stuff like that... It does make me feel good to be a sports fan in that regard....
