6. Bob Sapp
Sapp is the ultimate reminder that bigger doesn’t always mean better. At 6′ 5″ and 350lbs, this is one seriously big man. Originally, he wanted to play in the NFL, but it didn’t work out for him. So he turned to martial arts. Sapp has fought in MMA and kickboxing, mostly competing in Japan.
The US fighter had some early success in kickboxing, most notably beating Ernesto Hoost twice. But unfortunately, he has become a parody figure. After a ridiculous 12-fight losing streak stretching seven years, he finally won an MMA fight in 2018. To sum it up, this super heavyweight typically gasses out very quickly.
