The other part of the equation is that it is rare to have a legit hit tool and power. Those prospects with serious grades in both categories are top 15-20 picks usually, or the IFA that the Dodgers/Padres sign.
The org did draft for power and raw tools for a while in the 2010s (think V. Roache, Harrison, Gatewood, Lutz etc). Those players if they do not hit, the power is useless. Whereas a hitter who can get on base still has upside, and maybe can generate more power. So if I were to pick between the two, I would go with guys who can hit, or find a way to get on base, and hope that a few develop power along the way as they develop or grown.
That has been a big shift that last few years I think starting around 2016 - 2020, when that shift seemed to begin (Ray and Hiura were hitters who had power potential, and Mitchell was an excellent athlete). Since 2021 on that seems to be part of the MO - also going with the very Stearns like approach of scout what others aren't scouting (ie JuCo arms; pitchers with elite spin but lack of success; hitters who can hit; guys who are athletic to play defense anywhere), and throw in the occasional wild card (Misioroski in '22; Pratt in '23) who sign for big bucks.
Still I agree, the AA and high A clubs are in the bottom 2 in HR, and bottom 5 in SLG (although Biloxi plays in an 8 team league), Carolina has more power in their league (tops in SLG), but their SLG is bolstered by the league leading triples which speaks to their speed. Which is another tool we have in spades in the system.
So this could be the year to try to draft a power profile or two, so balance the good hitters, elite speed and defense that the system has.
