Him being a wrestling fan isn't positive. They don't want wrestling fans anywhere near the creative department because real wrestling fans tend to pick up gaping holes in logic and crap angles that have no business on television. I have a feeling Prinze will be finding that out soon enough. As mentioned before, Vince might use him as a show pony because of his name, but outside of that, I see very little happening.
There was an article published a week or so ago about how a Hollywood writer was hired because he had a Ph.D., although he was a big wrestling fan. The article mentioned how Pat Patterson gave him hell because he was viewed as some Hollywood guy coming in to ruin the business, and then when he mentioned to Johnny Ace about how he enjoyed his work in Japan, Stephanie gave him hell for talking like a mark.
