It could be that Krall was looking at the HR ballpark effect with France like he clearly must have done with Candelario.
While there wasn't a noticeable effect before 2023, there is a very noticeable effect covering the last two seasons, 2023-2024. The same hitting would have produced 31 HR's in Cincinnati's GAB vs the 20 HR's he's actually hit in 2023-24.
France has changed so much of his swing and plate approach the last two seasons that he's now become an extremely passive hitter who routinely strikes out or weakly grounds out, but when he does get the ball in the air, he's produced a lot of warning-track power, something that he could take advantage of when he's playing in Cincinnati. The excitement of that possibility should lead Ty to getting more balls in the air and being more aggressive at the plate (fewer stikeouts looking, fewer takes on good pitches).
The stark difference the last two seasons with the effect of playing in the GAB is what I'd concentrate on here. There's not a lot of positive things one can concentrate on with Ty France (besides his good personality), but this is definitely one of them. For someone who has produced about 1 HR every 3 weeks the last two seasons of his career and 1000 Plate Appearances of his career, there should be an immediate spike in the HR production rate at the GAB.
