When I began putting together this list of MMA‘s biggest knuckleheads, I started by trying to name as many stupid fighters as I could. That list quickly exceeded the necessary sample size.
Be more specific, then. What really comes to mind when you think of a knucklehead? Personally, I came to the conclusion that a knucklehead is someone who speaks or acts before thinking, in a pattern of behavior often (if not always) equally as detrimental to the knuckler as the knuckle-ee.
In other words, it’s someone who not only does dumb stuff, but who should know better. There’s are big, wet chunks of silliness in the stupidity.
So here are the 10 MMA fighters I think most fit that bill. Are there others? Yes, there likely are.
