#3 A slower journey back to WWE
There’s a fair argument to be made that Bret Hart began his slow return to WWE in 2005 because, as he struggled with health issues, he was ready to partner with the only organization that had the resources to properly celebrate his legacy. WWE was not only far and away the biggest wrestling company in the world, but owned the bulk of Hart’s career between its own and WCW’s tape library.
Were Hart still wrestling at that point, he would still be building his legacy, be it with Impact Wrestling, Ring of Honor, or abroad. As such, he probably would have felt a lot less urgency to make amends with WWE. It’s unclear how long his full-time in-ring career might have continued had he not had his concussion issues in WCW. Nonetheless, we can fairly guess that he wouldn’t have returned to WWE until the latest stages of, or after he’d finished his in-ring career.
