#7 Never sign again - Mr. Kennedy
One superstar who never reached his full potential under Vince McMahon is Mr. Kennedy. Despite being promised to reach the top of the WWE, many incidents coerced the company to think otherwise and releasing him.
For those who don't know, Kennedy was once scheduled to be a part of one of the biggest storylines in the business, with the former US Champion set to be revealed as Vince McMahon's son.
The storyline also Vince McMahon's limo explode where a death angle was also set for the Chairman but due to real life incidents regarding Chris Benoit's actual death, the Boss had to return to the squared circle.
Moreover, there were multiple rumors that Mr. Kennedy shared a pretty fractured relationship with John Cena and Randy Orton which eventually led the company to release him.
Since things have never been favorable for Kennedy ever since then, Vince McMahon might never consider bringing him back to the squared circle.
The Chairman definitely believes in giving opportunities at once, and if the superstar being offered the chances fails to deliver, there's an unlikely chance that he would ever put them in the similar spot again.
