I think for a lot of us it's not a practical issue of determining which team is which, it's that sports are wrapped up in a lot of nostalgia. One grows up watching their team(s) as a kid and can continue to do so through the seasons of life even as everything else is changing. So it's sad when tradition is thrown away and it no longer feels like you're watching the same thing anymore. In my case, I was obsessed with baseball as a kid but I stopped playing and stopped following the professionals when I went to college, met my wife, started my career, had kids, etc. Now I'm coming back around to follow baseball again and I'm often like, "What is this? This isn't what I remember." The uniform changes are part of that.
