I don't have a lot of hate for teams. The team I tend to hate the most these days is the Warriors... they've knocked us out of the playoffs so many times and I can't stand Steph, his celebrations and on court demeanor mixed with everyone kissing his ass all of the time, rubs me the wrong way. I only hated the Lakers when we were competing against them for western dominance in the late 80s and early 90s and then later hated them most during the Kobe era. I haven't hated any other team for a while though because we haven't been on a level where anyone is standing in our way of a championship besides our management.
I tend to just enjoy fun basketball games and great play unless it's standing in the way of our Blazers advancing.
