• ISO
• OPS+
  • For this, we can't take into account park factors, so instead, calculate the league average OPS (normalized to 100) and scale individual OPS according to the average

OPS+ will need to be restricted to the current season exports. This is because it relies on the league-average OPS. Previous season data will be potentially lacking considering some players retire, which causes us to not have their season data

wOBA would be an easy one to add as well https://library.fangraphs.com/offense/woba/
