Votto overhauled his approach because his plate discipline zen master thing he did as a 30 year old didn’t work as a 38 year old. I wouldn’t say he developed some weird habit.
In Barrero’s case, wouldn’t he be developing these same habits in AAA where he was striking out 35%+ of the time and struggling to OPS over .600? Not to downplay the risk, but if he’s playing hurt and struggling, then the risk of bad habits exists anywhere.
