inSec did that back in Champions Winter whenever he got a chance since KaKAO didn't like playing him in the jungle anyways, and it worked. If someone picks Shyvana or Trundle in solo q and you're going top, I highly recommend Olaf. Haven't played the Renekton matchup, I'm skeptical as to whether Olaf can actually win lane pre-9.
