#6 Bret Hart

Bret Hart was already approaching the end of his career by 1999. Even though he was seen as a megastar in WWE, WCW, and other promotions, he was always a victim of questionable bookings.
One of his most famous rivalries was against Goldberg, where the two became the main crowd pullers. Goldberg, who has never been known as a safe wrestler to work with, and is well-known for very stiff strikes, brought Hart near his retirement.
Even though Goldberg warned Hart about an incoming kick, Hart was unable to block the stiff sidekick and ended up with a severe concussion.
It was so bad that Hart starting having trouble remembering things and began suffering from emotional issues. After retiring, Hart has written columns in newspapers, contributed to Roddy Piper's autobiography, and acted in several movies, television shows.
Hart was most recently seen on television when he made a surprise appearance at All Elite Wrestling's (AEW) inaugural pay-per-view, Double or Nothing, to unveil the AEW World Championship.
