Another Danielson wouldn't make much sense kayfabe wise. But I guess that if Jericho "has" to drop the belt, TK would put it on someone that can help him get that TV deal he so desperately wants, Dragon and Cole are probably his only two options.
I listened to that interview and it was kinda funny how he confirmed every perception we have about him. If it was up to him, he'd be wrestling younger people on Dark all the time and not even be on TV much. It was interesting him saying that he would be champion if asked though, it's not like he's opposed to the idea, he just has other shit that makes him passionate about wrestling.
