Dude, there are way more dangerous sports than MMA.
Also:
Punching people in the face and getting punched isn't particularly "alpha". A true alpha is the leader of a group. The one who is at the top. In modern society the ability to physically fight doesn't put you at the top of everything else, since fighters often have people who have control over them without the need of throwing one single punch. As bad as this may sound, someone like Dana is actually more alpha than most fighters, because he is the guy in control, he is the guy with power.
Now, the biggest Alpha fighter in combat sports is Floyd Mayweather, since he is the one who has more power and control over other people.
