Has Cena been hit or miss in anyone else's opinion of late?

[Kane Knight]

This isn't a "Cena Sucks" deal. When he's been on of late, I think he's really been on. But it seems to me like there have been some nights where it'd be generous to say he was phoning it in, at least on the mic. Maybe it's out of his control, or something like fatigue. Maybe he really isn't as into it those nights. Whatever.

Never sure what to say abotu a topic like this, because I'm always readily certain people will infer that I'm "hating" on Cena, when if he wasn't doing a good job at least sometimes, I'd have no real reason to notice or complain when he wasn't. I'm mostly wondering if anyone else sees it this way, that it seems like some nights Cena's been giving 110% and some nights more like 70. Numbers are arbitrary, sentiment is not.
