This has been discussed as nauseam in the ORG, most recently in the "Liking Dusty More Every Day..." thread, so I thought I would throw my two cents in and see if anyone else in the Sun Deck has any thoughts.
The discussion is about Dusty trying to get Dunn to be more aggressive at the plate.
Many are saying that Dunn does not need to be more aggressive, that he does not take too many pitches, and JoJo seems to have stats to back that up.
I am an ex-college hitting coach, so I am somewhat qualified to talk about hitters' approaches to hitting. This is my take on Dunn.
First, all the stats that JoJo provided are pretty much meaningless, however thorough they are. The only issue is what pitches Dunn is taking, not how many, or how many compared to others. It is a problem if he is taking pitches that he can drive, and swinging at those he can't. RMR is somewhat correct when he says that that the key is pitch recognition, but he doesn't seem to fully grasp what that means.
Pitch recognition is not about being able to tell a strike from a ball, which Dunn is very good at (actually too good at), but being able to determine which pitches you can drive vs. which ones you can't. Sometimes pitches you can drive are ones that will be called balls, and some that you can't will be called strikes. A hitters should swing at the pitches they can drive whether they are strikes or not, and either not swing at the pitches that will be called balls, or try to foul off those will be called strikes.
Dunn's two main problems are that he is so concerned with only swinging at strikes that he lets go many pitches that he could drive, but he thinks will be called balls, and he is not very good at fouling off strikes that he can't drive.
This will result in exactly the numbers that Dunn puts up. Strikes out a lot, walks a lot, but crushes the balls he does put into play.
So Dusty is correct that Dunn needs to be more aggressive, as there are may pitches that Dunn sees that he can crush, but that he thinks are balls. This is especially true for power hitters. I think we all can agree that a guy as strong as Dunn should trying to drive every ball that he think he can, and not thinking about walks at all. I think that unfortunately, Dunn has bought into the notion that knowing the strike zone is more important that crushing every ball that you can.
