#3 Jason Jordan
When it was revealed that Jason Jordan was Kurt Angle's son back in 2017, WWE received criticism for it. For starters, Jordan's tag team with Chad Gable was among the best ones on the whole roster at that time. Secondly, the WWE Universe didn't think that Jason Jordan was ready to be a prominent singles player at that time.
However, with time, the 3-time Tag Team Champion proved why he was capable of being a bankable WWE Superstar. His slow heel turn towards the end of 2017 and beginning of 2018 made for an interesting storyline. All signs were pointing to him facing Seth Rollins at WrestleMania 34.
However, after Royal Rumble 2018, Jordan went under the knife to recover from a neck injury. While it was initially speculated that he would be out of action for over a year - similar to Edge's 2003 recovery timeline, things haven't gone quite to play for Jordan. It has been over two years now and there are no signs of Jordan returning to the ring
The fact that Jason Jordan had to move on from wrestling just when he was hitting his prime, and that he was robbed of an incredible opportunity to retire Kurt Angle at WrestleMania 35, was a pity.
