In many ways, Bob Holly's book was better than his wrestling career- no offense implied. As he mentions in his book, he never got a real push, was underpaid, and underappreciated for 15 years. It was refreshing to read about the perspective of a jobber to the stars in the WWE who was there for around 3-4 eras.
He actually was a good wrestler and performer but was always labeled as a "good hand" and someone who could be relied upon to test new wrestlers, work in tag and opening matches, and be an undercard roleplayer. He guesses it was because of his mic work or HHH buried him.
Bob Holly repaired his reputation with this book- beforehand he was considered a bully like JBL, but when he did his podcast book tour he came off as being personable, honest, and just stated his opinions from his point of view.
I think some of his opinions are too subjective because the front office never told it to him straight and he was forced to make up explanations for them. I guess they never had the heart to tell him he was never going to be a draw and was going to be a jobber for life to them.
