I grew up watching Tyson and I remember feeling physically sick when he got knocked out by Buster. He will always be one of my favorites.

With that being said I don't watch that much boxing anymore. I think promoters, like Don King, have ruined it. And idiots like Floyd "Money" Mayweather continue to drag it into the gutter.

I watch mostly MMA now and even though there are a lot of organizations. I feel like the UFC has the majority of the great fighters. There are a lot of other fighters that deserve to be great fighters but I don't feel they have been truly tested.

My Favorites:

Tyson
Georges St. Pierre
B.J. Penn
Anderson Silva
Cain Velasquez
Fedor Emelianenko
Gegard Mousasi
