#2 Drew McIntyre

Drew McIntyre's first run with the WWE started off in a promising manner but ended up with the Scottish superstar being paired up with Heath Slater and Jinder Mahal in the disastrous 3MB faction. However, following his departure from the WWE, McIntyre became a man possessed and a superstar who was hungry to make a name for himself.
The former WWE Intercontinental Champion did find success outside of the WWE but unlike others on this list, McIntyre was not employed by any global company and instead opted to make a name for himself on the Indie Circuit.

Shortly after his departure from the WWE, McIntyre became one of the mainstays of Evolve Wrestling, where he competed for three years and subsequently also made a grand return to his home promotion in Scotland, Insane Championship Wrestling.
In his first post-WWE match, McIntyre won the Evolve Wrestling Championship by defeating Chris Hero and went on to rename the belt as the Evolve World Championship, as the Scottish superstar successfully defended the title belt against some of the finest global stars in the form of Ricochet, Davey Boy Smith Jr., Marty Scurll, and even Johnny Gargano.
Simultaneously, on the other hand, Galloway was in his second reign as ICW World Champion as he defended his belt for more than 15 times against the likes of Killian Dain (then known as Big Damo), Aleister Black (then known as Tommy End), and even against veteran Doug Williams as well.
It is definitely safe to say that McIntyre was at the peak of his game right after his departure from the WWE, as he was at the helm of two strong World Championship reigns. In the meantime, McIntyre also won UEWA European Heavyweight Championship, initially becoming a Double Champion in ICW in 2015. And in the very same year, Galloway also defeated Johnny Gargano to win the Dragon Gate USA Open the Freedom Gate Championship to become a Double Champion in Evolve Wrestling.
