To continue what I started last month in taking situations that haven't happened yet but at this point seem unlikely to happen and talking about them instead of talking about things that have happened. Since his career kicked off John Cena has really been looked at a talent with a tremendous potential and thus far he has proven exactly that. Cena did start his career off very slow, but when it got going he very quickly became a top star within the company during a time in which the company really needed some new top talent. By the time Cena won his first World Title in 2005 he was something unlike anything else the company had in decades.
But now you look at things like the fact that Cena has been a good guy for over 15 years at this point and has pretty much also had the same gimmick for that time as well. For years internet fans have been begging the WWE to turn John Cena heel and allow the "franchise" of the company to not be a good guy for once. However, into his forties at this point the company has moved on from him and found their next "franchise" even though Roman is not on Cena's level it was time for him to be replaced. Even with this in mind it doesn't matter though that John will be able to turn heel at this point as he is part time player now and this makes it even tougher to flip him to the dark side.
Though there might be other ways at this point to be able to turn John heel it isn't extremely easy to turn heel a top star that has been a good guy. Keeping in mind the amount of members of the IWC that have been dreaming of Cena's heel turn I am not sure if at this point they'd care as much about the anticipated turn due to the ascension of Roman Reigns. At this point I think it is safe to assume that John will continue down the road of being the company guy until he leaves the WWE for Hollywood like many have before him.
This section has to do with moments that may have happened a little "Too Little Too Late."
