Walker or Olsen Start?

Which one would you start? I’ve been debating this all week long and looking for a couple more opinions.

Walker, it looks like Mathews is out and the titans just got blown out. I also find it hard to trust someone just coming back from an injury this late in the fantasy season when wins are so important. Another thing is the Panthers D should prevent any kind of shoot out and could make it more of a blow out meaning olsen could get some rest later in the game.

I have the same situation and I am playing walker. Carolina essentially said he would be on a snap count and coming off an injury I want to see how he looks before passing in a juicy matchup like walker has vs IND.
