3. Ken Shamrock
People are still willing to pay Ken Shamrock to fight, so he does.
Shamrock is a pioneer of mixed martial arts, and as such people will always want to see him compete. He is now in his 50s however, and hasn’t been competitive in decades. His last win in a UFC fight was at UFC 48 over Kimo Leopoldo in 2004, and since that fight he is sporting a 2-9 record, including a loss to Royce Gracie at Bellator 149.
