Is there a ‘code’ inside the cage?
There was one consensus among everyone I asked. Whether they thought there was a code or not, everyone agreed that this was just Quinton Jackson complaining.

What are your thoughts about a ‘code’ inside the cage? Is it ‘anything goes’?
Is Quinton Jackson right to complain about Jon Jones injuring opponents? Should fighters really be endorsing presidential candidates? What does it matter what Ronda Rousey’s mom thinks about her coach? And what would the author of this column tell his own daughter if she wanted to become an MMA fighter?

I was about to answer this question on my own and then I realized, wait a minute, I’m not an MMA fighter. How should I know if they think there’s a code of some sort that they are expected to follow? Then I realized, oh right, the way I should know is by asking them. So I did.
Last night and this morning I conducted a mini-poll on the issue to see what fighters thought about Quinton Jackson’s criticism of Jon Jones. I expected it to be fairly unanimous one way or the other, but actually, there was a lot of disagreement. So much disagreement, in fact, that when I made the mistake of including two retired fighters on the same email thread, they fell to bickering with one another about it. (I won’t say who those two fighters were, but one of them does a weekly column with me, and the other’s name rhymes with Jewelry Medzie.)
