The first one is obvious. Much improved jab. But the second was the way he kept Ruiz on the move, never really allowing him to set himself. Not sure if this was overlooked but I haven’t seen it mentioned as much. Ruiz only really had any sort of success fighting out of the clinch from what I can recall. Really impressive adjustment from Joshua in my opinion as he’s previously looked a bit static and stiff.
that is because very few people bother to watch legs in a fight. they usually watch from the shoulders up. Some will watch from the waist up. Very few watch from the waist down and just gauge that as both guys being equal anyway.
