I respect Cena cause he's carried the company for 10 years and the man works as hard as anyone, but I can't say he's one of the GOATs by ANY means. The fact is that he's carried the company because they didn't have anyone else and the WWE has propped him up specifically for that reason. It's easy to sell that much merch to kids when you've been kept over artificially and rarely lose.
You can say Cena is a good guy, reliable, a hard worker, over, a draw... he is those things but despite what WWE and even some wrestlers like Stone Cold THINK, Cena is not in the top 10 or even 25 of all time.
The only time Cena gets mainstream attention is when he's headlining Mania with The Rock, and that is because he is not one of the GOATS and no matter what anyone says he will never be.
