UFC 321 has the chance to shake up multiple divisions. Saturday's pay-per-view has two title fights, Tom Aspinall vs. Ciryl Gane and Virna Jandiroba vs. Mackenzie Dern, on the poster -- but it's the undercard that shows glimpses of the future.

UFC Vancouver, like UFC Fight Night 261 in Rio de Janeiro, had nine stoppages on the card. What’s crazier is, six of the finishes in Canada came in the third round or later.

History was made in multiple ways at UFC Vancouver, but none more significant than Drew Dober breaking Dustin Poirier's knockout record.
