It's not hard to "bury" a guy when all you have to say is "you have no experience in X"...
The problems with WCW, and perhaps TNA today, are well documented. Knowing what we know about Bischoff and the way TNA hired him and Hogan as a ratings boost, I'd say that you don't have to be in television to ask an obvious question like... "Well you didn't boost TNA ratings, so what do you have to say to that?"
I think that's a pretty honest question.
I also think that it's a stupid idea for some internet wrestling podcast type of guy to think that he can have Bischoff on and ask him any hard questions. Bischoff clearly comes into that interview with an upper hand and doesn't have any problem controlling the conversation.
