#4 Former WWE NXT Champion Keith Lee
Former WWE NXT Champion Keith Lee has had an interesting 2021 so far. Lee began the year by feuding with then-WWE Champion Drew McIntyre on RAW. McIntyre defeated Lee to retain the WWE Championship on "Legends Night" in January.
However, after scans revealed a potentially severe heart inflammation, Lee spent close to six months on the sidelines. The Limitless One was finally cleared for action and returned to the ring on RAW in July.
The former NXT North American Champion primarily competed in dark matches ahead of RAW and SmackDown. But he returned to RAW this past Monday under the name Keith "Bearcat" Lee.
Keith Lee and Roman Reigns have never faced off before in a one-on-one match. However, they did have an incredible ending to a Survivor Series tag team elimination match in 2019. The Big Dog and Bearcat were the final two competitors representing SmackDown and NXT, respectively.
Since then, fans have been desperate to see Keith Lee and Roman Reigns face each other one-on-one.
#3 WWE RAW Tag Team Champion Riddle
RAW Tag Team Champion Riddle has quickly become one of the most popular characters on the red brand.
Since WrestleMania 37, Riddle has formed an unlikely alliance with former WWE World Heavyweight Champion Randy Orton. Known as RK-Bro, Orton and Riddle have shown tremendous chemistry, despite their polar opposite personalities.
The duo quickly found success as a tag team, defeating AJ Styles and Omos at SummerSlam to become RAW Tag Team Champions. However, Riddle is known primarily as a singles competitor. The Original Bro has never shared the ring with The Tribal Chief in a one-on-one match.
Perhaps the upcoming WWE Draft could see Riddle or Reigns switch brands, making The Big Dog and The Bodacious Bro squaring come to reality.
