#3 Curtis Axel and Tye Dillinger
Curtis Axel is a prime example of a failed second-generation superstar. Though he had won the Intercontinental Championship with Paul Heyman's alignment, this pairing also couldn't save his career from falling to the ground.
Despite being the son of Mr. Perfect, he couldn't live up to the hype that he should have. The possible factor for his failure might be his lack of in-ring skills or maybe some other reasons.
And as far as talking about Tye Dillinger, though he is not a second generation superstar, he has some great in-ring skills to show-off, but despite this, he has failed badly on the main roster, though being a mainstream star back on the NXT brand.
So, be seeing the situation that both men are currently in, it's better for them to try there talent somewhere else such as Impact Wrestling. Both men may find success working under the company.
