The "all or nothing" swing that the Twins have pushed has a lot of holes in it. Students of that swing throughout their development Larnach, Wallner & Julien had success & Kepler adapted that swing & was successful. But MLB pitchers easily adjusted, Like Jeffers who ditched that approach last year, Kepler & Larnach adjusted. Unfortunately, Wallner & Julien have not & suffered greater than-expected regression & have had trouble adjusting their swing. Like Wallner, Julien needs to go down & reset & it won't be easy to unlearn the old swing & relearn a new one.
