I did a quick google I was not as lazy as I thought.
"Even minus the replay views, the numbers were still strong enough to make his fight with Alexander the most watched MMA fight in 2009.
With his Elite-XC fights and his two fights with the UFC, Kimbo Slice's last four matches have been firmly placed in the top 10 watched MMA fights in history."
Note this was written in 2010 so of course it have changed, but it tells me that what people watch and quality is not always the same. Some people seems to think views = great fighter. Which it is not..
