Looking at Kim Do-young, those three—Choo Shin-soo, Ohtani, and Ichiro—are on a whole different level

No matter how I look at it, even if Kim Do-young goes to the MLB, I don't think he'll come close to those three.
Choo Shin-soo: single season wRC+ 150, WAR 6.5 or higher
Ichiro: single season wRC+ 135, WAR 4 or higher
Ohtani: single season wRC+ 180, WAR 9 or higher
Even Ichiro, who is the lowest among those three, wouldn't be an easy feat to reach.
