If you're not familiar with the Bellator/Alvarez saga check it out, it's pretty interesting.
I thought Chandler would win but Alvarez did an amazing job at being elusive for the first 3 rounds, throwing jabs and keeping away from the cage. Chandler gassed and Alvarez took over. Great fight!
If Alvarez lost, he would have been let out of his contract. Now they have a champion who doesn't want to be there, and are paying him a lot. He has one more fight on his contract, and if he wins that there is a chance he will vacate the title and leave, which makes them look bad. That's why Dana called it Karma
Bjorn's response was funny, he called it the fight of the year and if that's karma, he's happy with it. However if you look at his reaction, he's obviously not happy with Alvarez being champ
