The goal of every franchise is to win championships, I'm just being realistic about this team's chances with the current roster, I want them to win championships and thus I want them to rebuild. I still root for them every game, but naturally they lose many of them because they're not good enough, which was already known, hence the call for a rebuild in the first place.
I root for them to win, but also acknowledge that if they lose it is likely best for our long-term prospects of winning championships because this is a flawed team with a paper thin farm system and spinning our wheels as a mediocre team is purgatory; we're not good enough to win and we're not moving backwards now to move forward later.
If you don't understand that, fine.
