Agreed on YS RF helping Soto defensively, offensively his power is more towards left-center/center so it won't help him much on paper. I personally think the concern about Judge in CF is overblown. he played there 78 times two years ago in his 62 HR season, he loves playing there, and they clearly got Grisham to play there as much as possible, late in games etc.The move to the Yankees is perfect for Soto as the small right field should boost his power and will likely mask his defensive shortcomings. Hitting in front of Judge could also mean more strikes, so, in theory, more total bases with a slight reduction in walks. I think that combo is going to put up massive offensive numbers next year but I do wonder about the risk of potential injury to Judge playing Center Field.
Maybe, Bryce Harper spent the whole season before his FA not even considering diving for a ball, and had the worst defensive numbers of his career by far that season.As for Soto improving on defense, one anonymous exec (so, take this with a grain of salt) said: “Juan Soto can be as good as he wants to be. He just needs to decide he wants to be.” If the issue is effort/attitude, you'd have to think Soto will be immensely motivated as he approaches free agency.
