I'm hoping that his contract is up at the end of the season and he is replaced. As mentioned earlier, I haven't seen enough consistent good play from the D to feel confident that Yeo was the entire problem and Van Ryn doesn't share some blame. When our D is playing well, I generally feel that it is mainly Petro, Bou, Parayko and Dunn having good games as opposed to them following a system that gets more out of them than they have. Those are 4 very talented D men and (outside of Dunn) should be able to have success without much help from the D coach. With that said, I'm not sure any of Petro, J-Bou or Parayko have exceeded expectations over the course of the full season.
With all of that said, most of that is 'gut feeling' stuff out of me and I would not want to make the decision based on just the info/knowledge I have. I won't be mad if he's brought back.
