First I will do the extra credit.
The Miz must NOT turn face. He could be the next Triple H (heel) in a year/two
at least. But a face turn will be bad. Just bad. I myself don't see Miz as face. I just can't picture it.
Now
who needs a turn.
Kane
Friendly giants don't work. Maybe the Lil' Jimmies like it when the Kane smiles then destroys someone, but I don't.WWE kind of teased Kane turning before he left, I mean he faced the Mega Face of Smackdown, but I want to see Kane return (whenever that is) as a heel. He is a great worker, many have said, and his 2010 WHC run was not very noteworthy**, but his promos really entertained me.
**Sidebar- I did not understand his feud with Undertaker at all. Undertaker returns, and he never won a PPV match (besides WM 27) after that. Their feud included the dropped ball storyline of Nexus assisting Kane to win, and nothing really coming of Paul Bearer turning on Taker. **
Ezekiel Jackson
Same reasons as above. Friendly big guys (most of the time) do not work.Zeke was the last ECW champion, for crying out loud! Now he sporadically wins on Smackdown. Zeke needs a heel turn and a mouth piece for a manager.
]Titus O Neil
Sorry for only listing heel turns so far, but heel turns usually help a star more than a face turn. Storyline wise, O Neil doesn't have a WWE contract and is trying to earn one on NxT. We all know he has a contract, so I will count him as a roster member. O Neil needs to turn heel, stop the dog barking, stop the Hornswoggle buddying, just stop. O Neil has the look, but he has the look of a heel. His match on NxT and Superstars this week showed him being aggressive, and that could easily make him a heel. He should turn on Hornswoggle and be a heel.
Kofi Kingston
I dislike happy go lucky characters. On Smackdown in 2010, Kofi showed an aggressive side that I really liked then and like now. Now, as part of Air Boom, Kofi is happy go lucky x10.
I would really like to see Kofi turn heel by turning on Evan, costing himself and Evan the tag team championships, and then feuding with Evan, ending Air Boom.
Yoshi Tatsu
I believe Yoshi could play the classic evil foreigner. He's already got Japanese entrance gear and face paint, now he should say something along the lines of "Japan is so much better than America" "America's a disgrace" or something. Instant heat. (Hey, Sin Cara spoke, why not Yoshi?)
Trent Barretta
Trent is WWE's expert jobber. He jobs, but looks good doing it. On NxT a few weeks ago, he actually won a match!
But if he goes back to his DudeBuster persona, he could make his way up the card, at least to lower mid carder.
Daniel Bryan
Before you say "Daniel Bryan? Heel turn! No, no no, let me quote this dude and dispute the heck out of him!" let me explain.
Bryan is on a losing streak, yet he is Mr. Money In The Bank. He could be the next WHC when ever he wants to (storyline wise.) He could say how he has busted his butt for years and he finally gets to WWE,and no body aprreciates him for what he did on the indie scene (on TV, he could say what he did to get to WWE) He could go on a different roue, and say that he respects nobody because no one in the WWE has worked as hard as him to get to the WWE.
