Cena's being creative?! Lol Well, let's see. "You left us for 7yrs", "You're here for yourself", "The notes on the wrist"(The more he point that out, the more I believe it's a work), "Your insults are immature"(If you can't outdo someone do something else), "You're phony, dwayne"(It's like when you throw an insult at a little kid and he throws it back at you. Cause if my memory serves me correctly, it was Rock who called Cena a phony first), I guess that sums up Cena's promos for the last couple of weeks. The funny thing is, whenever Rock goes hard on him he goes back to his "kissing ass" mentality(Thier first confrontation in chicago). I mean, last monday, Rock completly destroyed him in that concert, and his response on his twitter was "The old Rock is back!!"?! Really?! That's all you've got?! The guy claimed that he banged your mom, and that's you're response?!
Just because Cena is getting edgier "doesn'T" mean he's being creative. Plus, the "Old Rock" that you been missing was all about the catchphrases, also.
Cena is being more creative than The Rock at this point. You listed 5 points that Cena uses.
The wrist writing was already reported as a shoot. The fact that you continue to doubt that shows that you're willing to accept your own blind denial as evidence over a backstage source. Yes, there is a chance that it's a work, but until any source provides evidence that it is anything other than a quick shoot, you have no basis for your opinion.
Rock's insults are immature. I don't see how anyone can dispute that. Many of us said that before Cena did, and it's a relief that someone is finally echoing our sentiments. It is part of Cena's gimmick to do this; Cena didn't change just for this feud. He has been like this since facing CM Punk last year.
I think the "phony" argument is lame from both The Rock and Cena, but for the sake of your misguided argument, Cena technically said it first during an interview several years ago that influenced The Rock's first comeback promo.
Let me add one more major point that Cena has made: "I need to win this for my legacy". That argument single-handedly is better than anything The Rock has said at any point during this feud. Cena passionately explained why he wants and might even need to win this match.
Now, let me give my analysis of the things that Rock has created since he came back.
"You look stupid" - Yes, the epitome of creativity right there. Look, I can just speak for myself here, but if someone told me that when I was in High School, I would have shrugged it off then, so why would I expect a grown man to sell that?
"You remind me of fruity pebbles and kung pow chicken" - ...seriously?
"Why don't you stick stuff up your butt?" - That's a real winner.
"I have sex with way more women than you" - Oh good, now Cena knows that he's more likely to get an STD just by shaking Rock's hand.
"Your male fans are virgins" - I've made enough sarcastic statements in a row, so I'll just call this factually inaccurate.
"You have female genitalia" - Again, I can only speak for myself here, but I don't really care what Cena is packing under his camo shorts, whether he resembles Chyna or Ron Jeremy. If it really matters to you, maybe you're watching the wrong kind of program.
"You would have lost the revolutionary war." - Wait, what?
"I had lots of sex with your mother." - My goodness, I bet Cena can't believe that someone said something about his mother. That must really burn him up.
I'll give you that The Rock has said more (after all, he gets 20 minutes every Monday for this nonsense). Nevertheless, judging by the content you posted about Cena and this, I'd say that Cena is doing a good deal better.
