I'm just trying to figure out who Cena has buried. Let's revisit his recent feuds:
Rusev- In a love feud with Lana, Summer Rae and Ziggler. Only superstar I remember in recent memory to get spots every week, despite being out with a real injury. Ziggler is even off shooting a movie, I mean healing from a trachea injury caused by Rusev, and Rusev still main evented.
Lesnar- Became champ, headlined WrestleMania, headlined Battleground and is about to headline SummerSlam
The Shield- Reigns is in a big feud with Bray Wyatt and is the supposed actual future of the company. Ambrose has been featured each week and involved in some good storylines of his own (you could make the case he's not being used enough though). Rollins, well, he's only the WWE champion.
Bray Wyatt- Always loses, but he's supposed to be a bad guy (for now) and bad guys usually end up losing feuds. Gets the longest promo every Monday night.
Kevin Owens- Remains to be seen, but Cena gave a fresh out of NXT star prominent play for three months.
So, in summary, Cena definitely buries everybody.
