What's the most one-sided rivalry in your sport, and does the underdog have any real hope?

[Slay40]

Every sport has at least one rivalry where, despite the label, the actual results have been overwhelmingly lopsided for years or even decades, one side keeps showing up as the favorite regardless of form, and the so called rivalry starts to feel more like a formality than a genuine contest

What makes these interesting to actually discuss isn't just naming the imbalance, it's digging into why it persists, sometimes it's genuine talent disparity, sometimes it's a structural or financial gap that's hard to close, and sometimes it's something more psychological, a team or player who's simply gotten inside the other side's head to the point where the result feels decided before it starts

Curious what everyone's pick is here across any sport, and specifically whether you think there's genuine hope of the underdog side actually closing the gap anytime soon, or whether this is one of those rivalries that's just settled for the foreseeable future regardless of what either side does differently
