#2 Roman Reigns
The Big Dog is one of the most well-known WWE superstars today, as Roman Reigns was the face of the company until he took a hiatus after being diagnosed with real-life leukemia.
However, Reigns has had a very successful career in the WWE as he is a Grand Slam Champion, having most notably held the WWE Championship three times. He is also the cousin of WWE legend in The Rock, and has been in the main event Wrestlemania many times.

But before Reigns wrestled, he was also playing in the NFL for two years as Joe Anoaʻi in the Defensive tackle position. Reigns played for three teams: the Minnesota Vikings, Jacksonville Jaguars, as well as the Edmonton Eskimos.
Reigns only had 9 tackles whilst being in the NFL, which lead to him retiring from professional American football in 2008 and signing with the WWE.
