Not really. 2 weeks ago Dunn needed protection in the lineup. He was being killed by EdE's lack of production. EdE should be sent down, they clamored.
Now EdE is killing it, yet Dunn is still in a funk. Must be the lineup slot.
Except, for his career, Dunn has a higher OPS in the 5th spot (.906) than he does hitting 3rd (.809) or 4th (.900). Amazingly, 6th is better than those choices as well. He is hitting a robust .910 in that spot. 2nd is the leader at .942.
So, to answer your question, I really don't wonder about it too much. I think that it is just a pat excuse for Dunn's struggles. First it was no protection. Now it is the lineup slot. Next on the list is "luck", since his BABIP is only .250 this year.
While I agree that Dunn is under a microscope on this board, I would love to see others in the lineup get the same leniency from the masses. Griffey isn't declining, Phillips just isn't protecting him. EdE's struggles in the first few weeks had more to do with the lack of protection or lineup spot than we thought. Valentin wasn't providing enough protection. You know, things like that.
Sometimes I think that many here believe that the roles of others on the team revolve around getting Dunn to hit. Dunn's in a slump? It's obviously on the guys hitting behind him. Maybe we should rearrange the entire lineup because Dunn isn't hitting.
If that's what it will honestly take, then he can walk at the end of the year. Paying him what he gets paid should necessitate his production no matter what the situation. It doesn't matter how the stars are aligned that day.
