I like Walker's power potential, but would it be tough to fit him into a major league lineup with all the other fixtures and highly touted prospects that fit the same mold- big power/high strikeout guys like Arcia, Vargas, Sano? How many of this type of hitter is ideal to have in the starting 9? I understand that none of the other 3 guys I mentioned are guaranteed to be long term fixtures, but for arguments' sake let's suppose they are.
