This is the eternal problem with the Cena we have now: he's done everything a top guy can manage to do, yet managed to do it in such an unremarkable way that no one gives a shit anymore.
Fight the Boss? Every major face (especially faces of the company) have went through this feud to the point where thats almost how you can tell a face has made it. Taker had the Buried Alive thing with Vince, Rock was the last centerpiece of the Alliance angle and the corporation, HHH and HBK had DX (and the Montreal Screwjob as well), Orton terrorized the McMahons (as a hell, though it still fits) and Stone Cold fought...well... everyone, but everyone can remember every instance of him whipping Vince in a variety of ways. What has Cena had? His run-ins with heel Vince were far from extensive and barely memorable, his run-ins with Vickie were just as bad (this AJ thing JUST got interesting after like a month), he was a background figure in ousting Bischoff even though he FU-ed him, and his program with Laurinitis was not only forced as hell, but stolen from right under CM Punk, which meant every fan with internet access was against it from the start. Score: 0/1
Get a Love Interest? Macho Man and Miss Elizabeth, HBK and Sherri, Edge and Lita/Vickie, HHH and Stephanie, hell even King Booker T and Queen Sharmell: all of these big pairings worked, undeniably. All attempts to do this with Cena failed. Cena+Maria? Anyone remember that? Cena+Mickie that Kenny still complains about? Cena+Hoeski/Eve, as hilarious as it was, was a one night thing, and Cena+AJ failed before it started. I was gonne throw in a Cena+B-Squared joke, but nah. Score: 0/2
Slay Giants? This is one thing that Cena has excelled at. Cena vs. Big Show at WM for the first time was cool. Seeing Cena bust out the 1st FU on Rikishi was crazy. Seeing Cena hoist both Edge and Big Show on his shoulders was a mark out moment in an otherwise forgettable match. But we've gotten to the point where it's almost not special anymore. I'll still give it to him based on nostalgia, though. (Score: 1/3
Big Money Matches? Cena's damn near drawn that out. Let's be dead honest here: Cena is a major draw for kids and maybe women. Adult men, long known as wrestling's primary market, could give a shit. I'm starting to see women and kids join the CenaSux Bandwagon now too, which sucks for him. The last Cena match that drew crazy like it should for the face of the company was Cena and Rock, and that was destined to draw with credit due to both men. Problem is that most only wanted to see Cena get his ass kicked by their nostalgic hero Rocky. He can't beat the odds anymore, so big money matches hardly work anymore, and if they do, they all have lurking variables that take more credit than he can. CM Punk vs. Cena worked because it was more Punk vs. the World at that point. Cena vs. Rock I already explained. Cena vs. Lesnar was almost all hype for Lesnar's return (plus, once again, to see Cena get his ass kicked), and many went nuts and lost faith after Cena won (on a side note, Punk/Ryback at HiaC outsold this, which is not a good sign). Cena vs. HBK, you say? Great as it was, I remember the IWC and even the most casual of fans losing their shit when Shawn didn't win at WM. No one really cared for Cena vs. Big Show this year. Cena vs. Batista did not become the legendary explosion of star power it was expected to be. Cena vs. Orton was done to 5 deaths. Cena vs. Nexus almost worked, but we all know how that went down. Also take into account how the product went on without him and how eager the fans were to get behind other faces whenever he went down (Hardy, Ryback, Orton, etc.) All in all, Cena, in the last 5 years, doesn't really have the drawing power we thought he had, does he? Score: 1/4 Speaking of Nexus...
Make or Break a Faction? Every major face had, at some point, some legendary involvement in a great faction (or at least tag team), whether they joined one, created one or killed one:
Hogan had the NWO and Mega Powers, stories which speak for themselves
Rock headed the Nation and then the Corporation before killing the Alliance, not to mention Rock and Sock
Steve Austin had 2 Man Power Trip, headed the Alliance and knocked a lot of power out of the Corporation and DX
HBK had plenty: The Rockers, NWO, DX, Kliq, the Diesel thing, etc.
HHH had many as well: McMahon-Helmsley, Evolution, DX, Corporation, 2 Man Power Trip to name a few
Edge had his Familia alliance, and earlier was with The Brood and Taker's ministry
Orton and Batista had Evolution, while Orton also did Legacy
Taker has his Ministry and the Corporate Ministry
Booker was the only major WCW star in the Alliance, and the hilarious stint with Goldust, and the brief NWO try.
That's just to name a few. Cena's had NONE.They had something going with Nexus, but he buried the living shit out of them, which I don't have to explain as it is still fresh in the minds of many. Score: 1/5
Character Change? This has been debated to death, and I won't do it again. We all know how this ends up. Final Score: 1/6
All in all, Cena's time is up. To be honest I think that if Orton and Hardy hadn't been so unreliable and if Punk hadn't been so opinionated, he might have been replaced already. I think Ryback is being primed to take his spot, just you wait.
