I would say it’s irrelevant whether JBL “caused” the breakdown. What is relevant is whether JBL bullied or treated Ranallo unprofessionally. Ranallo has never said “nothing” happened. He’s been very careful with his wording on that and simply said his “leaving” had nothing to do with JBL. If JBL was totally innocent in Mauro’s eyes he would have issued a strong statement saying the JBL thing was fabricated but instead he’s been evasive with his answer on that. Couple that with Mauro originally hinting that something with JBL did happen, his friends all going hard after JBL at the time, and especially JBL quietly leaving the announce booth and I think common sense says something did go down there. The severity of which is clearly unknown. But with WWE valuing its reputation I think they would do a lot to try to keep a story about bullying in the work place under wraps and would pay a good chunk of change to get a NDA in place to do it.
This nails it right on the head for me. If JBL was this "poor innocent Texan" as people ITT are saying, Mauro would have set the record straight. What motivation would he have to not do so? But all the things that went down at the time, more in the moment when Mauro walked, are way stronger indicators towards his feelings on JBL, those things you mentioned. Of course he's going to say different things months later, when he's back with the company on a more comfortable schedule.
The thing about it is, I think Mauro's telling the truth- to a degree. The WWE schedule is brutal, let alone when you're juggling 4 or 5 other things outside of wrestling as Mauro was/is doing. But if those things about JBL never happened, Ranallo would have set it straight. He's carefully avoided saying he had problems with JBL. The mental stress of dealng with a known bully like JBL, especially with Mauro's condition, COUPLED with the insane schedule is enough to do a lot of people in.
Some people seem to have trouble understanding why Mauro doesn't just go in on JBL, put it out there. Mauro's a smart guy, and most people that have had paid employment understand workplace politics. JBL is one of Vince's boys, he's worked for WWE in some capacity for almost 25 years. Shitting on him, even if it's true, is career suicide. And also, if it was false, Ranallo would earn brownie points with Vince by clearing Bradshaw's name. So, looking at it from that perspective, Mauro's guarded answers on the subject speak fucking VOLUMES.
