It's a work folks. She stands to make a ton more money on a rematch than she would facing any other new competitor, or a repeat. Mark my words she will dominate the rematch forcing a rubber match where the money will keep rolling in. Before anyone says, "she got ktfo, who would do that on purpose?". I say to you, would you allow someone to knock you out for an eight figure sum a few months later? I sure would.
Rousey fights were getting to the point where people didn't wanna spend $60+ to watch an arm bar victory within the first two minutes. Just like wrestling in today's environment. You can't have someone win for two straight years and expect people to stay invested.
