#2 Murphy (WWE SmackDown)
WWE SmackDown Superstar Murphy had a decently successful 2020. The former Cruiserweight Champion joined hands with the Monday Night Messiah Seth Rollins and the two won the RAW Tag Team titles.
Murphy played a massive role in Seth Rollins' rivalry against Rey Mysterio but later turned babyface and joined hands with the Mysterio family. WWE also started a romantic angle between him and Aalyah Mysterio.
However, after picking up a victory over Seth Rollins, Murphy disappeared from WWE TV for months. Upon his return, he surprisingly once again approached Rollins and the entire Mysterio family storyline was scrapped.
While his return in that manner made little to no sense, WWE might continue his push from last year by having him win the Andre the Giant Memorial Battle Royal on SmackDown this week.
#1 Cedric Alexander (WWE RAW)
Former Cruiserweight Champion Cedric Alexander's main roster career looked to be in jeopardy last year. However, things turned around completely for him when MVP recruited him into The Hurt Business. Alongside Shelton Benjamin, he won the RAW Tag Team Championship and had a dominating run with the faction.
However, this past week on Monday Night RAW, WWE Champion Bobby Lashley kicked him and Benjamin out of The Hurt Business. This has raised questions as to what this will mean for the future of Cedric Alexander.
If WWE was impressed by his time in The Hurt Business, he could be given a proper singles push, and that could start with his winning the Andre the Giant Memorial Battle Royal this year.
