3 WWE Superstars whose careers declined and 3 whose careers thrived in 2021

#4. WWE RAW Tag Team Champion Riddle's career thrived in 2021

Riddle is one of the most talented individuals in WWE today, and he has proven it throughout 2021. The 35-year-old debuted on the main roster in mid-2020, joining SmackDown. However, a few months later, he moved to Monday Night RAW in the 2020 WWE Draft.

In December 2020, Riddle began a feud with the then-United States Champion Bobby Lashley, which they continued going into 2021. Although The Original Bro lost to the Almighty in a U.S. title match last January, he captured the championship a month later at Elimination Chamber after defeating Lashley and John Morrison in a Triple Threat match.

Riddle held his first-ever title on the WWE main roster for two months before losing it to Sheamus at WrestleMania 37. Despite losing the championship, Riddle's career was about to take another positive turn. In the weeks after WrestleMania, The King of Bros joined forces with Randy Orton to create RK-Bro.

RK-Bro is probably the most entertaining team in WWE today. The unlikely duo began their chase for the RAW Tag Team Titles in August. They successfully defeated AJ Styles and Omos at SummerSlam to capture the championships and have held them ever since.
