Alistair Overeem – The Biggest Legacy in Combat Sports
Beware of an old man in a profession where men die young. Despite age and battle-damage, few have had the tenacity of one Alistair ‘The Demolition Man’ Overeem.
At 40 years of age, Overeem retired from the sport of MMA with a professional record of 47-19-0(1NC), he saw the final bell in only 8 of these 67 fights. But If 16 of his losses were by finish, how can he be the greatest of anything?
Well, Overeem is a multi promotional champion and held belts in multiple organisations at the same time. He competed for near-enough championship status in every major promotion he was in. He also fought the very best for a majority of his career and took no shortcuts nor any breaks.
What sets Overeem apart however is his ability to jump to an entirely different sport (from MMA to Kickboxing), and still defeat stiff competition. Plus, his uncanny ability to return from adject adversity.
The Legacy of The Demolition Man

I refer back to the ‘tenacity’ part in the opening line. Despite tough losses and major set-backs, Overeem always fought and beat the best. He dominated multiple world-class combat organisations whilst facing down a murderer’s row of past and future champions.
He hopped sports frequently, and took out kickboxing world champions whilst holding major titles in MMA. Alistair was one of the first multi-promotional, multi-sport champions, and held major titles in MMA and kickboxing simultaneously, whilst achieving accolades in submission grappling too.
