3 reasons why WWE used so many NXT stars in Royal Rumble 2019

#2 - To introduce the next NXT call-ups to the WWE Universe

Andrade had debuted in the 2018 Royal Rumble match and now he is an integral part of SD Live in 2019

Last year, WWE had very few NXT superstars in the Royal Rumble match and thus, they had to promote the upcoming stars' main roster arrival for a long time before their debuts took place. In the past few weeks, WWE heavily promoted the 6 new NXT call-ups before using them on the main roster, so as to give their proper introduction to the WWE Universe.

If we look at the superstars used in the 2 Royal Rumble matches, all of them will be on the main roster before 2019 ends. So, the Royal Rumble was the best stage to give the WWE Universe a glimpse of what is to come on the main roster. Also, this has opened up an opportunity of using any of these superstars this week on RAW or SmackDown Live, with some background.
