Kai is in the top mix for the O title but he is not and never will be Ronnie Coleman. Coleman's structure was far superior.
I don't see Kai as Mr. Olympia. He is too boxy. However, I believe he will be in the top placings this year at the O. Somewhere between 3rd and 5th depending on if others are in shape (Victor, Heath, Wolf, Jay, and Dex).
