You obviously know more about this than many of us, and I agree that just making changes for changes sake is not the answer. Having said this, over the last few years, we seem to see many players advance to the majors that don't seem to have a grasp of basic fundamentals. From not taking proper routes on fly balls, to missing the cut-off man, to not running smart, etc. To me, this speaks to a failure somewhere in coaching at the minor league level, and means they should be making changes. These are basic things that really don't have much to do with talent, and are things the Twins continually miss on. In addition, the Twins philosophy regarding pitching has been an abject failure, they just don't advance quality arms to the majors. The staff down there may just be following marching orders, but at some point the guys hired to teach have to be responsible for the fact that few, if any ever do well at the major league level. For these reasons, I think the Twins should be looking closely at all of their coaching, including at the Minor league level and they should make changes. I am obviously not qualified to determine if Gary Lucas was part of the problem or part of the solution, but in general support the Twins making changes in areas they have been doing poorly in, and that does include development pitchers.
