With NXT Takeover New Orleans on the horizon, it is expected that we will see several WWE NXT talents making the transition from ‘developmental’ to the main roster, with debuts expected on the Raw after WrestleMania 34 and on SmackDown Live, as has happened over the past few years.

Since NXT has effectively become a third brand there have been many debuts and they have been done in different ways, with some wrestlers being announced ahead of time, some turning up at incredibly random moments and others popping up by attacking a member of the roster.

Each way is effective at the star, gaining that initial pop from the crowd, but it is often what happens in the following few months that determines whether or not the superstar gets over with the WWE Universe. After all, not everyone watches NXT and because of that, even some of NXT’s biggest stars fail to make an impact on the main roster and today we rank the five greatest call-ups and the five biggest flops from NXT.
