Also replying to comment by "example1" above that the manager and Cherington are intelligent .....
1. O.K. I am getting to be a "conspiracy theory" guy about these developments...... the conspiracy: Ferrell and Cherington are intelligent puppets manipulated by Henry to save as much money as possible whilst maintaining PR.
2. But let us now consider the batting coach issue brought up by jad. I heard John Kruk talk about JBJ extraneous foot motion during JBJ's swing. Maybe there is now an effort by Red Sox to increase the power of JBJ?? He went to an open stance, seemed to improve, then started to regress again. He keeps striking out on outside fastballs now, without trying to drive them to the opposite field.
If an emphasis on a power stroke is at work, that could be a mistake. In the 1950s there was a centerfielder, Richie Ashburn, who had a 311 B.A. for his 12 years with the Phillies. He was a brilliant defensive outfielder. Because of his lack of power Ashburn lost out on the first go round of voting into HOF, but was put in years later by the Veteran's Committee. I do not recall that Ashburn had anything like the throwing arm of JBJ.
Ashburn averaged only about 2 H.R. a year!
