There are two ways the lineup could be improved.
Middle of the line up Outfielder, and you move/bench Span
Middle of the line up 1B, 2B, or 3B and you move/bench LaRoche
I prefer the second if anything because if you are trying to bring in pop, LaRoche doesnt give you OBP, Span does
I don't think either happens to be honest with you
To do either correctly, the terms in years can not restrict you from Keeping Desi, Harper, Stras, JZ. Thats the core of this team, Rendon to early on to muddy that picture.
I think Cano messes up that last part, so I don't want to do it. Also, while I don't want to judge a man's personality I don't know, he strikes me as the type that will be done caring before the ink dries.
