This goes back to my question from, oh, about 15 pages back.
Would you rather have one of the best DH's in history (40 years, but still history), or someone who was a pretty good CF (top 5-10 during his peak)?
And keep in mind, Edgar could've been a bad 3B for most of those years (see Cabrera, Miguel). He owned a glove. They just wanted him to focus on hitting.
