While several weight classes might have claims to be the deepest or most interesting in the UFC, no other division is as high-profile both in and out of the Octagon as lightweight. Any time a top-tier matchup is announced at 155 pounds, it carries a sense of potential tectonic shifting with it. Sure, that sounds a little dramatic, but so is the division – in a good way.
