While I'm rolling my eyes at Literally's Juolevi comment, I'll defend his Edler comment somewhat.
You could feasibly argue that Edler hasn't necessarily lost a step since 14/15 (although it looks like he might this year), and that his drop in play can be attributed to the fact that he formed an absolutely dominant pairing with Tanev and played together the whole year in 14/15, and has been doing a pretty good job single-handedly baby-sitting defensive liabilities since. Combine that with the fact that Edler will always stops caring and look completely abysmal when the season gets out of reach, and you could very reasonably argue that his drop in play is misleading.
That said, I don't see anything that could lead one to believe that he's actually gotten BETTER since 14/15. That sounds like clear hyperbole.
