I'm not arguing whether he's a good o-line coach or a great o-line coach or even a ****ty o-line coach. His comments about Cutler were what FC is focusing on and I don't think that will be an issue, call that glass half full if you like. In a perfect world the team would be have great coaches who had never made a public misstep. Kromer screwed up, some would argue by admitting what he said anonymously, now he's moved past it. Is it a hurdle? Yup. Can it be overcome? Yup.
& it doesn't to Ryan. It could get messy, but, it doesn't have to. I can guarantee that he won't make this same mistake twice. Rex just hired himself the most loyal o-line coach he could find.
