I agree fully on your first point. There are very few players who can succeed long-term when they have no ability to get on base via walks.
As for pitching staff management, that is kind of an unknown to fans, but I think it's an important consideration. The pitching does not seem to have suffered under Dingler. However, given how well the Tigers staff of chaos did last year and given how important Rogers apparently was to their success, I can see where they might weight his defense heavily in any platoon. I am confident that Hinch will get it right.
