#2 Paige

The most recent instance, this has yet to play out fully, but if true, Paige’s retirement from wrestling is one of the saddest moments of all time.
Paige came into wrestling as a woman who made changes to the Women’s division. She was the face of the Women’s Revolution that WWE wanted. The problem lay elsewhere. She had health issues from the beginning of her life, with abnormal curvature of the spine being one of the main problems she faced.
She came from a family that was completely involved in wrestling and did not let this stop her from living out her dream. She won the Championships there were to win in WWE, but she would suffer an injury.
Then came the issue of her relationship with fellow wrestler Alberto Del Rio, who was extremely frustrated with WWE. Del Rio would leave the company and Paige would accompany him to other wrestling promotions while suspended for substance abuse from WWE. The two of them even got engaged, but recently the two broke up and Paige came back to WWE.
Once back, she led out the stable of Absolution, and it looked like her career was back on track. This did not last, and in a house show match with Sasha Banks, Paige suffered an injury after a kick by Sasha. Given all her previous injuries this one was a bit more serious, and it was announced that Paige was withdrawn from the Women’s Royal Rumble.
While nothing has been finalized yet, credible Wrestling Journalists have mentioned that her career is at an end, and she will work in WWE in a non-wrestling capacity. If this is true this is one of the biggest wastes of potential in wrestling in recent memory.
