It depends on who you get to replace Lee. In my hypothetical where we get Overbay as well, you don't lose much defense at 1B. CPatterson (or anyone else), do you know anything about Overbay's reach? I'm a pretty big fan of his, but I don't know much about his defense. Would you consider him to be a gold glove candidate? Admittedly, I haven't seen him play very much, but he scores very highly with statistics like Rate, RAA, and RAR throughout his career. His ZR isn't very high compared to other 1B, but that's probably less reliable than the previous 3 in determining performance.
