Cool. You acting like it’s obvious to root for your direct rival just because of some monetary gain, as a fan, is weird. Not difficult to understand, but more so difficult to understand why a fan would root that way.
Your general tone towards people is also in that category, but that’s a different story. I rooted for St John’s to lose because I have disliked them since the late 90s. I’m a fan, I like the extra dough to help my team but I’m not actively rooting for my team’s rival. I guess that is weird.
