I think of "plateau" as meaning this is as good as Malloy's going to get, and I believe most of the rest of the world thinks of it as that, too. I have my doubts as to whether Malloy has plateaued. I think he has room to get better. I don't know whether that includes his glove, but if .700 OPS is his plateau, then we might as well start looking for ways to cash him in.
