5. Bob Sapp
This next man is currently on a 13-fight losing skid, and they’ve all come by way of finish. Bob Sapp has yet to win a professional MMA bout since March of 2010, but is still going strong in competition today despite his recent troubles.
Sapp is a monster of a man with a height of six-foot-five and weighing an astonishing 329 pounds. ‘The Beast’ started his combat career right off the bat by juggling both kickboxing and MMA competition.
Despite his size, Sapp has never been a dominating presence in either sport, as both his kickboxing and MMA records are losing ones.
Sapp’s kickboxing record sits at (12-17), while his MMA record sits at (11-19-1). Sapp is currently 42 years old and is surely nearing the end of his combat career after earning his 13th consecutive MMA loss.
