While 2021 might not be completely repeatable, he's a launch angle tweak away from being close. When you say "years removed from being a difference maker", it makes the guy sound like he's on the wrong side of 30 - He's 25 and just entering his prime. His Savant page is fantastic, outside of his LA.
To me, this is a guy who has a 130 wRC+ floor over the next 7ish years with a possibility of converting him back to a fly ball hitter and have him turn into the superstar bat that he has the potential of.
