I feel like Ruiz gets a lot of help from McCoy. He's a real wild card sandwiched between Penning and Lemieux. He really struggled badly last year when McCoy had to help both him and Hurst.
I agree that Ruiz isn't particularly good or at least he isn't consistent, but I think he is better than the backups and he works well with McCoy. I'm not sure I can ever have confidence in this line, but I'm not sure they can get back to being fine until McCoy gets back. Ruiz having to help Penning and whoever is at Center is not a good idea.
