#3 Nik Lentz
With 38 fights since 2005, Lentz is a seasoned veteran who still manages to stay active every year.
The Lightweight has been an ardent student of Mixed Martial Arts for a while and has fought guys like Islam Makhachev, Danny Castillo, Chad Mendes, and Hacran Dias. Not as many heavy hitters as the others but still impressive regardless.

The reason why the American has managed to stay knockout-less is his ability to rarely get hit during a fight.
