Sorry but this post just doesn't add up.
First things first: MMA has never and had and probably will never have a name that can compare with the popularity of an Ali and Tyson. Those names are known on a global scale in fact you must have been living on a different planet if you haven't heard of them. Kids in remote villages somewhere know who those guys are.
Now I can pretty much guarantee that in the UK (where MMA has some popularity), the average person on the street has no idea who any of those MMA names that you just mentioned are. MMA fans obviously will have and the more casual fans have probably heard or Lidell, Ortiz, Lesnar (due to WWE) and maybe one or two others.
Now onto the boxers. I mentioned Froch as a response to the comments that there are no warriors/exciting fights and that happened just over a week ago so it is fresh in my mind. Froch has not been well promoted so he doesn't get much attention despite being a good fighter. He kinda lives in the shadow of Calzaghe here. Then we have David Haye - I washed his most recent fight against a washed up Ruiz in the casino a month or so ago and have never seen the place so packed out. David Haye is a HUGE puncher and a very exciting fighter to watch. Far more popular already over here than any MMA fighter. Then we have Amir Khan who is also well promoted and very exciting to watch due to his speed, power and also his slightly weak chin.
What I'm saying is not to be fooled into thinking that these American MMA fighters are that popular on a global scale. You say the average person on the street would only be able to mention Ali, Tyson, Mayweather and Pac but certianly over here that is at least 3, probably 4 more than MMA. Maybe it's different in the US but until an MMA fighter earns even 1/10 of what Mayweather and Pacquiao earn then I'm struggling.
Don't get me wrong, I still like SOME MMA and it has been marketed VERY WELL to its target audience but my posts are a response to idiots like Joe Rogan who claim 'boxing is dead' despite all the facts. It's like having short man syndrome.
