If you want to make wins against John Cena mean absolutely nothing, you give one to Ziggler or Corbin, I guess.
The guys who have pinned Cena in the past two years off the top of my head are Nakamura, Styles, Ambrose, Rollins, Wyatt, Reigns, Strowman, Owens, Elias, a lot of those being as recent as in the past year or so. The only name who stands out there is Elias, although they're building him up and he's actually over.
Ziggler and Corbin? That devalues a win over Cena imo, and you can't have Cena put over everyone because then it'll mean nothing in general, plus he still needs to look somewhat good for when he wins his 17th title.
He didn't put over Balor, he's not going to be eating pins to Ziggler or Corbin lol.
The only guys on the main roster who haven't pinned Cena that should are Joe and Rusev if they decide to ever get behind him and actually push him.
