I'll admit when Usyk decided to move up to HW, I didn't like his odds. In first few HW fights, he appeared a little uncomfortable in there. He lacked the pure physically I thought was needed to compete at the highest levels of the division. Grow into it he did though. He's an amazing boxer and like the best, he finds a way to win. He's highly skilled but the mental aspect of his game is just as big a part of his success.
I think it was a fair and logical prediction. It turned out to be wrong because Usyk is maybe a top 10 all-time fighter. Pound for pound
