That is true, she could have. We'll never know, though... although it is remarkable how he has been "in the right place at the right time" almost all the time throughout his career.
They might come to mind because they are finishers, but truthfully, even finishers are nothing but yet another move with a fancy name. Pedigree = Double Under-hook Face Buster, really. The Stunner is nothing but a Jaw Breaker. Etc and so on. But it's how and when these moves are performed... we agree there. I think it's impossible to have an unlimited or un-repetitive move set. It is possible to change the order, and even still I think there is only so many combinations you'd come up with. Austin was repetitive in the ring. So was Rock. So is HBK. When he gets whipped and does that Turnbuckle Spot, admit it, you know it's coming, but you still mark and why? Because no one does it like HBK.
Plus, coming back to it, the WWE has a formula that "works" and that they like to have followed. No Main Eventer, no signed superstar, is going to risk losing a spot and the money by not following it.
He doesn't need to look invincible, I agree, and at the same time it's part of his character, as "The Game," "The King of Kings." His character is untouchable, unbeatable, undeterred... can it be played differently? Of course. Is he going to do it? I can only hope. And I would like to see him put over some of the younger stars more than he has (or at least differently), and I would like to think that when the time is right, he will. I think that he is not the asshole people paint him to be backstage, and he is not the one with the final word on everything -- Vince is, as many people have pointed out. And while family is family, business is business, and Vince McMahon is all about business, so I don't see him having a problem telling Paul to "job" to someone, and I don't see Paul having a problem doing it. Is the current situation telling us differently? Maybe. But history is not, history shows us that Vince is not afraid to do what is needed (Punishment for the Clique Incident), and if the wrestler is smart and doesn't take it personally, then that can only be seen as maturity and a good thing in Vince's eyes.
Just on that note, the state of wrestling backstage I think has changed tremendously since the 90s and the Attitude Era, and so it isn't as much wrestling oriented anymore as it is entertainment oriented (duh, right?) and so that plays a large role in who we see, how much of them we see and how they win their matches. The wrestling comes second to selling tickets and merchandise, and so "they can afford" to be repetitive in the ring and what-have-you. But the truth is you ca't please everyone. You take the good with the bad, enjoy this and hate that -- that's how it goes.
Yeah... about that... lol. Can't blame me for trying to use that argument though.

And at the same time, I don't know how much of a flagship show SmackDown really is these days, so maybe they can afford to be a little more risque there than on Raw...
