Nah I can't hate the colors, or the name. I only hate the success. If the Lakers are doing poorly and relying on ping pong balls/development to mark a successful season, then there is no rivalry to me.
To me the rivalry is just with the Wizards and Raptors. You might be able to throw the Cavs in there, but the Cavs' fanbase don't seem to acknowledge the Celtics as a rival. They're only lookin out west.
For the last game their fans were telling themselves that the Cavs weren't trying to win the game, rather they were experimenting with D-Will, and it was hilarious that the C's still almost lost at home. So ya idk about if the C's-Cavs are a thing.
