I don't think it's in the WWE rule book. If I recall, the only rule in the WWE rule book is that WWE can change anything at anytime to fit their needs.
The 30 day rule was used when superstars were chasing the championship and that champion was avoiding the challenger and any other superstar as well. It would seem, for now, nobody wants the US title. A lot of this is WWE not knowing what they are doing with the Shield, as it seems they are turning them face and, after teasing a split, it looks like they are on the same page like days of old. But with them not knowing what they are doing at this time, I wouldn't expect to see it defended until maybe Extreme Rules, unless they do split The Shield and do a triple threat for it at Mania.
At the end of the day, though, I think it legitimately gets forgotten and will go the way of the European Title.
I've never seen somebody be so right, and then so wrong, all in the same post.
You're absolutely right that the only rule is the WWE can do whatever the hell they want, whenever the hell they want, to tell the best stories. Why aren't we complaining about Undertaker and Kane breaking the laws of physics? That seems like a bigger deal than Ambrose breaking the 30 day rule.
As for The Shield, I mean...I don't even know what to say. You really think the WWE doesn't know exactly what they're doing and what they're going to do with them? It's called teasing. It builds tension, it builds interest, it builds suspense. Just because YOU don't know what they're doing, you think they don't either? Come on, man. You're better than that.
Yeah, I know the rulebook doesn't matter anymore, but it just hurts believability when the champion doesn't even defend his title.
Believability? Really? It doesn't hurt believability when Undertaker summons a lightning strike from the sky that hits the ramp right in front of somebody? It doesn't hurt the believability when somebody is thrown through a table and gets up and keeps wrestling a few minutes later? It doesn't hurt believability when two people are in a ring exchanging unchecked kicks and punches without ever bleeding or bruising, let alone any broken bones? It doesn't hurt believability when a wrestler suffers through a submission hold for a minute or longer without breaking a bone or tearing a ligament within seconds? There are a LOT of things in professional wrestling that are less believable than a champion going 30 days without defending his title. In fact, just about everything in professional wrestling is unbelievable when it comes down to it.
The 30 day rule is a bad holdover from the days of kayfabe, and in particular, the AWA and old NWA. It was only ever invoked to strip a babyface of a title so that said babyface didn't have to drop the belt to a heel. 30 day rule clauses rank up there with Dusty finishes, IMO. Wrestling is scripted...we all know this. There is no contender ranking. There is no 30 clause for title defenses. These are constructs that were put in place to mirror other sports in a time that wrestling still pretended to be sports, at least in public.
Bingo. I'm going to repeat what I said in the thread about the WWEWHC title unification, because it's just as true here. Title belts are PROPS. They're just like the crown Jerry Lawler wears, or the cowboy hat JBL wears, or the robe Damien Sandow wears, or the flags the Real Americans carry. They're props. They don't actually signify anything. That time has long passed, and it is never coming back. People who want title belts to have meaning are probably the same folks who want them to go back to four or five PPVs a year...it's called nostalgia. People romanticize the way things were when they were younger. Hey, I get it. I play old video games on Wii more than any current game. But times change. Professional wrestling is no longer treated like it's real, and it never will be again. That's just how it is. And with that goes the significance of title belts. That's just how it is.
If they don't have somebody defend the title within 30 days, who cares? I love the response that said if no guy can't defend the title every 30 days he shouldn't be champion and they should give the title to somebody who will. Umm, what? Wrestling is scripted. The writers decide who the champion is and how often he defends the title. I really, really doubt Dean Ambrose has been refusing to defend the title for the last few months. If they take the title off him, they're just going to put it on somebody else who won't defend it either. What's the point of that? Leave it on Ambrose until they find somebody else to give it to, and the appropriate storyline to go along with that.
The only time the inactivity rule can legitimately be used is when somebody suffers a legitimate injury and has to give up their title(like Cena, Edge, and Batista in recent years), though usually it takes an injury that will keep them out more than a month for them to strip a guy of the title.
The sooner people stop acting like title belts are more important than they are, the better off we'll all be.
