If Karimi shows up in the shape he was in at last years World's, I could see him giving Sadulaev some troubles. Sadulaev is an absolute monster though. Karimi should get out of his side of the bracket, though he'll have a tough Rof16 match right away against Ganev in all likelihood, which he should win. Same deal with that American J'den Cox that people have been hyping, he should get past him even if it might be a tough match. Would make for a fantastic final.
