Nope. There's a lot more money in Holly Holm vs Ronda Rousey. If Holly loses to anyone but Ronda, she's most likely retiring from the sport. She'll be 34 years old soon, she's been fighting professionally for 13 years. She has no children. Biological clock is ticking, and if she loses a fight before fighting Ronda, it will potentially set her back a couple of years. More, if she gets injured. And considering her age and experience, she's likely to get more and more injured in the next years, if she keeps fighting.
This was the right fight to make. It's not optimal, but it was now or never.
UFC made the right call. It would have been a tragedy if Holly never fought Ronda.
