10 NXT stars who were brought up to the main roster before they were ready 

#3 Enzo Amore

Enzo's promo ability is the only reason he's survived on the main roster

The only reason Enzo Amore was promoted to the main roster was because of how popular he and Big Cass had become down in NXT and the company wanted to cash in on that.

Enzo and Cass were fine for a number of months, until their split when they were pitted against each other and Enzo's poor skills in the ring were finally revealed. When he was tagging with Cass, Enzo only had to perform a few moves and leave the rest to his partner, he was unable to do that in a singles match, which revealed all of his flaws.

Amore has since gone on to become Cruiserweight Champion, which is a shock since every wrestler on that brand is more experienced and accomplished than the former NXT star which has made him public enemy number one over the past few months.
