Why do u think Cena has to win cleanly to retain the "Embrace the Hate" gimmick?
Anyways here are my reasons as to why Cena wouldnt win cleanly:-
1)First and foremost, let me point out it would be a shame for wwe to let someone like cena beat someone like rock cleanly, it just shouldnt be happening, if u HAVE TO put Cena over him then atleast make him win in a heelish way, Cena just doesnt deserve the opportunity to go over the rock cleanly. - Cena carried the company on his back for 6 years becoming one of the most recognizable faces of course he deserves it.
2)If Cena does win cleanly, the whole storyline will become boring, they will prob handshake, or cena will prob destroy rock after winning, which are very predictable. Whereas if Cena doesnt win cleanly, Cena can start a new angle of gimmick. The heelish type of guy, who will go through any means to destroy his opponent. - How does him beating The Rock post match not turn him heel?
3)If Cena doesnt win cleanly, we can see him face the rock once again, maybe at summerslam, maybe at next year's wrestlemania. - If he beats him clean beats him post match Rock wants revenge, rematch set up?
4)The storyline can be like this, While cena is about to loose to the great one, someone interfere and gives cena the win, maybe kane? maybe vince? maybe johnny ace? He then starts his own team, something like the NWO or Evolution, Rock can then face him at summerslam again and loose, or face a member of his team at summerslam and either win or loose, cena and his team then terrorizes and dominates the show throughout the whole year, at next years wrestlemania rock forms his own team and we have a 3 vs 3 or 4 vs 4 team match between cena's team and rock's team. Rock's team wins, Cena accepts defeat and shakes rock hands, rock leaves, after that cena's team blames cena for the loss and attacks cena, hence cena turns face and starts a feud against his former heel team.
This will be a MUCH MUCH better storyline than them just shaking hands, or cena just embracing hate imo. WWE is really in need of a faction like this. - They can't handle factions not to mention we've in the past year and half we've had Nexus, New Nexus and the Corre. Stables need to be spread out other wise it becomes like TNA where every year there is a stable with the same objective. I'm not saying your wrong as many people enjoy stables but I personally don't.
4)Rock said he will be avialable even after wrestlemania, maybe even untill the next wrestlemania, hence cena winning cleanly, this feud will end right there, if they try to continue the feud even after cena winning cleanly, it wouldnt be as interesting. - Once again John attacks him post match setting up a revenge angle which is exactly the same as Rock winning dirty, isn't it?
Good post btw.
