#4 Jeff Cobb
After a successful career in amateur wrestling which included representing his native country, Guam, in the 2004 Olympics, Jeff Cobb made his professional wrestling debut in 2009.
Cobb got his big break while working for Lucha Underground, where he worked from 2015 to 2018, under the ring Matanza Ceuto.
He won the Lucha Underground Championship in his very first match and would remain undefeated in the promotion for a long time before losing to Rey Mysterio.
Cobb currently works for PWG, ROH and New Japan where he is the current PWG World Champion and the former ROH World Television and IWGP Never Openweight Champion.
Despite his huge size, Cobb is a very athletic performer and can pull off some gritty aerial moves.
Cobb is one of the busiest wrestlers on the independent scene today and 2019 is shaping up to be a great year for the Hawaiian-native.
