5 WWE Superstars whose careers lasted less than a year 

#4. Former WWE NXT North American Champion Leon Ruff

Leon Ruff was introduced to the WWE Universe as part of several jobber matches on RAW, SmackDown, and NXT before he was officially signed to the company.

Ruff became a WWE Superstar in October 2020 and became a part of the NXT roster. As part of his debut match, he was able to knock off Johnny Gargano and become NXT North American Champion.

This reign was a short one since Gargano won the title back the following month at Takeover: War Games, but it was a win that put Ruff on the map.

In the months that followed, Ruff was part of several feuds on the Black and Gold brand and was even able to make it to the quarter-finals of The Dusty Rhodes Tag Team Classic alongside Kushida.

This seemingly wasn't enough for WWE, since Ruff was surprisingly named as one of the released NXT Superstars when the company cut their budget at the beginning of August 2021.

This means that Leon Ruff's entire WWE career was just 10 months.
