Kim Do-young has such great tools that I think he can hold his own in the Majors.

Kim Do-young's rate of growth relative to his age is insane.
When looking at players who struggled after moving to the Majors, they were often players who relied solely on their contact tools in the outfield.
While it's hard to gauge because Kim Do-young's quality of contact is so fast for the Majors,
he is a player who can play the infield and possesses both great power and base-running tools.
I don't think players with this level of tools are common even in the Majors.
