Of course taking a knee is unpopular. This is a combat sport.

I'm not saying it's bad. If someone gives all they can and knows there is nothing left then save it for another day or retire.

But people are bloodthirsty. Especially people who like combat sports, like boxing. Taking a knee is submission. Viewers want people who are gonna act like they will put it all on the line in the ring. Problem is when you got $10 mil in the bank and another $4 mil coming for the fight your not going to do that unless you are a crazy mo

And specs like crazy mo's.

It's risk/reward. If you are getting paid 7-8 digits then people don't care if you gave it your all they want to see you put out or get shut out.
