Cena burying people is overblown. Besides Wade tha Gawd he doesn't HHH his opponents. Plus those obvious statements is not something most people would put together. KENTA isn't a household name, neither was D Bry's indy gimmick, and Macho Man's stuff is minor. So Cena bringing up these things is fair game and really important to the feud unless you're already an insider. Punk's whole game is to call Cena a phony and a fake kiss ass which alot of people on the outside agree with. So it goes both ways with the obvious.
He didn't bury anyone? He didn't dominate to no end in 2005, 2006, and 2007? They didn't have DX tap out to him back to back WMs? They didn't have Angle almost assassinate his character and credibility to put Cena over the end of 2005 for no real reason considering how fans were so against him? Edge had plenty of momentum after winning the belt in at NYR 06 and got good ratings in the aftermath of ending Cena's reign but they took his ass back down 3 weeks later and put the belt right back in Cena's hands. It took damn near a conspiracy at One Night Stand 2006 for RVD to get that big win....he destroyed the Miz in 2009 over and over and over again. He beat Wade Barrett in like a 4 minute squash match last year like he was a everyday joke. He's never put over Ziggler at all. He's crushed talent after talent.
The only guy he hasn't dominated is the Undertaker and I would say Kane..he doesn't beat him all that much either until this year with that stupid ass storyline that wasted everyone's time.
And sure the statements are not what the causals would get but those smark b*stards in Montreal understand. The thing is..others have to be handicapped so Cena can look good on the mic in any form. He's been killed on the mic by Wade Barrett, Punk, Cripple H, Lita, Edge, Christian, the Rock on a Facebook/Youtube promo no less, Carlito...the guy is a complete overrated joke. That's his format on the mic now. Rant and rave outside of kayfabe to sound more than he is. He's good at that..he's good at memorizing lines in that conjecture but that's it.
