I disagree that the MiLB stats are roughly equivalent.
Campbell 2024: 20 HR
Grissom 22 and 23 combined: 22 HR
Plus, the questions about Grissom's glove were shown to be well founded while he was in WOO last year. Campbell is a better defender and has a much clearer power projection. Grissom has been a waning prospect ever since he peaked at 22 in 2020.
