3. Dan Henderson(MMA Record: 29-11)
http://www.youtube.com/watch?v=dRlv9pDERVw Remember Wanderlei Silva's near six-year title reign? This man ended it.
An olympian turned Mixed Martial Artist, Dan Henderson slowly became one of the most popular American MMA fighters behind his Granite Chin and patented "H-Bomb" right cross that has put legends to sleep in a split second. He got his start at UFC 17, winning the Middleweight Tournament before signing with Pride and amassing a record of 13-4 over six years en route to winning both the Pride Welterweight and Middleweight Titles, the first to do that in the promotions history. After Pride folded, Hendo came back to the UFC to two title shots in two different divisions, but fell short in both fights to Quinton Jackson and Anderson Silva. Several fights later, and one
historic knockout, Henderson signed with Strikeforce, and won the Strikeforce Light Heavyweight Championship over Rafael "Feijao" Calvalcante in his third fight with the promotion. His next fight, he KO'd the legendary Fedor Emelianenko, who was widely considered by some to be the Greatest Fighter of All Time. Hendo is also nearing the end of his career, but he will always be remembered for his knockout power and his unbreakable heart.
