Hmm, who has the best mic skills in "today's" WWE environment...let me break it down like this:
Here's the order, and I'll explain why afterward:
1 - Edge
2 - Chris Jericho
3 - Orton
4 - MVP
5 - The Miz
6 - Christian
7 - Cena
8 - JTG
9 - CM Punk
10 - Ted Dibiase
Why #1 for Edge? - I've been watching Edge ever since his debut, pretty much. I've never seen anybody improve in the WWE as much as he did. He went from simply 1/2 of some tag-team to the top wrestler in the WWE. His mic skills are in a word, amazing. He flows nicely, he has different tones for different emotional situations, and he's believable enough for anybody to "mark" out. He mentally raeps Jeff Hardy, whom is one of my favorite wrestlers, but sucks on the mic, and pretty much out-talks everybody else with ease. The only person so far that's going to give him a real challenge is Jericho, being that he's on SD! now.
Why #2 for Jericho? - Chris Jericho was always good on the mic. Regardless of whether he's a face or heel, he speaks with ease and confidence. However, I do feel the intensity he emits while speaking as a heel is amazing. He knows how to work a crowd. Now, I do understand, his lines are written word for word most of the time, but you can give anybody that same piece of paper and I can guarantee you that they won't do it with as much authenticity as Jericho.
Why #3 for Orton? - Orton is the man, simply put. He shows everybody the way a heel is suppose to be on a mic. Yes, he's monotone, but he's like that for his current gimmick, and it fits very well. It helps get him over even more. I like the fact that he speaks monotonic, but once he gets angry, the sound from his vocals emit at 5x the amount, with increased bass and range, while his face turns red and clenches inward with his veins solidifying out toward the audience. Everything fits fine.
Why #4 for MVP? - We can pretty much all agree that he was better on the mic as a heel. It's hard to cross over from heel to face and vice versa, so cut him some slack. However, he is still a pretty good talker regardless. When he came out on Raw after the draft, and owned Orton on the mic, as well as calling Rhodes + DiBiasse "Abercrombie Models", I marked out for a lite minute or so. I was like, "Yoooooo, MVP just went in..." But yea, he def knows how to work a mic, so give him about a few more weeks, and he'll have the whole "face' situation under control.
Why #5 for The Miz? - The Miz really knows what he's doing on the mic. A lot of us usually paid more attention to Morrison over Miz...no homo...but after the split, and surprisingly putting The Miz on WWE's top show rather than Morrison, I'm sure we can all see it was a great choice. Miz really knows how to work a mic, and get himself over, drawing crazy heat from the audience most of the time. What he said to Cena, like "Unlike 12 Rounds, everybody is going to see this match" or something, I marked out like crazy. He said things to Cena that others would only keep to themselves. His push is well deserved.
Why #6 for Christian? - Christian is a funny dude. He has taken some notes from The Rock, since his "peeps" quote is based off of Rock's "the people". However, he does know what he's doing. He stays havin' Swagger sweatin' and angry. "Thufferin' thukatash!" Dude is grimy, lmao...
Why #7 for Cena? - Yea, people say a lot of things about Cena, but when it comes to mic work, he's really good on it, especially in his heel days. Regardless of his "6 moves", or sucking up to the crowd, he says what he has to say and for most of the time, does it well. He does not need to say anything to get him over, as the WWE has put him over so far he can lick his own buttcrack. However, the intensity and emotion he shows during his promos, while many may feel, including myself, he is trying to be like "The Rock", he does it well.
Why #8 for JTG? - I know I'm going to get heat for this one, but he is pretty good on the mic. He doesn't get a lot of mic time, due to the failing tag-team division, but he always does great. "Yo yo yo yo yo yo yo yo yo YO!" I love that line, and the audience does too. But besides that, he speaks well (in relation to his gimmick), and knows how to work an audience and talk to the ladies. "Yo why every week you stay losin'?" When he said that to Layla El I marked out big time. So believable, lmao...
Why #9 for CM Punk? - CM Punk is does a good job when confronted by heels, as proven during his confrontation with Jericho & Edge. He says what he has to say on the mic, with confidence, but he def knows how to back it up. You can see through his wrestling, that he has trained for an immense amount of years. All the kick combinations and multiple technical moveset, they make you believe that the pushes he receives are believable. Saying things like, "Anyways...so as I was saying..." when Jericho cried and left the ring, makes him believable and realistic.
Why #10 for Ted DiBiase? - Ted, while overshadowed by Orton, you can see this guy has a bright future in the WWE. He speaks very well and articulate on the mic, showing confidence in what he does. He definitely outshines Cody Rhodes in terms of mic skills, and will be on the level of Orton very soon.
And that is my list of who I believe are the best on the mic in WWE today. I know there will be people who disagree, but you guys have to remember, that this is a forum. Disagreements will lead to very detailed and heavy discussion, making us all smarter in the world of wrestling.
