7. Charles Oliveira vs. Michael Chandler (2021)
Oliveira’s story is great because it’s so unlikely. The Brazilian MMA fighter joined the UFC as a young man. However, he struggled for consistency. He had a mediocre 10-8 record in his first 18 fights with the promotion. Oliveira showed flashes of brilliance but struggled mentally. In some fights, it appeared as though he gave up. Also, he missed weight on four occasions.
Then out of the blue, something clicked. He went on an incredible nine-fight rampage and won the lightweight championship. The BJJ expert broke many records on the way to the belt. First, he achieved the most submissions in UFC history. Then, against Michael Chandler, he went even further (via Sportskeeda). He knocked out the American and claimed the record for the most finishes in the octagon.
