I can agree with his approach to the business even though I think he needs to know some of the history of pro wrestling.
You have some wrestlers who let passion blind their business senses. They end up going to the wwe with these expectations and once they spend some time there they realize that things won't turn out the way they planned. The wwe can be very draining. Just look at jtg and Zack Ryder for example. They had the passion, but after their ideas were rejected the passion was no longer there. That's why I can respect guys like the young bucks and aj styles for realizing that just because you're offered a wwe deal don't mean it's going to turn out well. They can still make good money somewhere else without losing the passion for the business.
I wish wrestlers would stop hopping to the wwe just because of the name value. A good half of the roster is probably frustrated because the wwe is fickled.
I have no probably with Brock seeing it as a job tho and not having any passion for it. You have some sports athletes that just do it because their just made for the job.
Some of the biggest names in the industry came into the industry looking at it as a job. Guys like the Ultimate warrior, big show, Kevin Nash, and Goldberg has always been about the money. Then you have others that came into the industry with passion, but it left after a while.
As long as the job is done right and the performance is good, it's okay(although I'd prefer passionate wrestlers).
