I've had trouble keeping my interest in wrestling since Jericho left. And I would love for him to come back--it would definitely make me more excited about watching, and I wouldn't be 2 and half months behind on programming to watch on my DVR list.
But at the same time, I think he was smart for doing what he did--he so far hadn't sacrificed wellness for the business, and hadn't traded in his body for wrestling success.
He hadn't sustained any major injuries, or been left with chronic problems to wear on his body and psyche. I think he saw the condition of many of those around him, and decided he wanted a different fate--that he and his family deserve better.
I'm sure he's torn, because this business is obviously in his blood, and wrestling is his gift. But he likely has serious reservations about the possibility of ending up like so many past and present in the business.
He has been my favorite since I started watching 8 years ago. (I was Y2JFan back in the day)
And I miss his long hair. But the highlights are pretty.
