#1. 2020 was the first year of John Cena's WWE career in which he didn't wrestle on WWE RAW
Fans of John Cena know that the 16-time world champion has transitioned into a role as a part-time star with WWE in recent years. Cena's only wrestling appearance in 2020 came when he took on The Fiend in a Firefly Fun House Match at WrestleMania 36.
Though Cena appeared on SmackDown in February to announce his retirement and the fact that he wouldn't wrestle at WrestleMania this year, he was confronted by The Fiend. This clash set the stage for their match.

John Cena has appeared on RAW several times over the past two years, but it's interesting to note that the last time the former world champion wrestled on WWE's flagship show was on January 14th, 2019. There, he took on Finn Balor, Drew McIntyre and Baron Corbin in a fatal four-way match.
So 2020 was the first calendar year in John Cena's career since his WWE debut almost 18 years ago in which the star failed to wrestle a single match on RAW.
