IDK Meteos has shown to be one of the most capable junglers in NA if not the world, his ability to almost read the other jungler was the most impressive skill of his.
With that said he can not shotcall well at the start it nearly looked fine, but losing so much allows your emotions to run high.
Of course most of use thought lemonnation be shotcalling but apparently they tried it and it didn't workout ether.
I don't think this decision is based on a matter of skill but more a desperation to avoid relegation.
They need there shootcaller and they need him in a position where he can do it, so that is ether mid(but they are training incarnation to be LCS caliber), Support, or Jungle. I think I would have gone with support but could be other reasons why the picked the jungle.
All in All, C9 is in a spot where I would expect major changes next split as long as they avoid relegation.
