The main card of UFC 331 delivered shocking moments on top of shocking moments, building pound-for-pound resumes. First, Sean Sharaf secured his first UFC win as the biggest underdog in promotion history, submitting Olympic gold medalist Gable Steveson in just 12 seconds. Then Arman Tsarukyan reminded everyone why the current crop of UFC lightweights may be the best ever with a devastating walkoff knockout of Mauricio Ruffy.

Flyweight champion Joshua Van followed it all up with a performance that should place him among the 10 best MMA fighters in the world right now. Van is a top five pound-for-pound fighter — and at just 24 years old with less than five years of pro experience, his rapid ascent is unprecedented. After his dominant performance against Alexandre Pantoja, who looked determined but ultimately outclassed, Van proved he's legitimately as good as just about anyone in the entire sport.

This was one of the most technical fights of the entire year, against one of the best flyweights of all time, and Van ended up running away on the scorecards. His athleticism, confidence, and natural finishing ability combined with exceptional technical skill make him a complete fighter.

Are we living in the greatest lightweight era of all time? The history of the UFC's lightweight division is rich — from 2016 to 2020 when Conor McGregor became double champ and Khabib Nurmagomedov dominated. But this upcoming chapter has a chance to challenge all that, with Ilia Topuria, Paddy Pimblett, and Tsarukyan as three legitimate superstar storylines who are all rivals.
