Couldn't agree more with the bolded part. It's also hard to get the newer/younger fans to care about a history that never won anything of note.
Do you recall the 20 for 20 ceremonies? It was almost embarrassing how little interest was shown by the people in the stands for most of them. History is something you need to experience first hand to be meaningful, and if you experienced it, you don't need to be taught it. We need to be more concerned with making history than teaching it.
It's also been so long now that the younger fans of this team weren't even old enough to even remember seeing the Metrostars play and the rest weren't even alive.
