Mamluk warrior here taken as a young boy from the Caucasian Steppes by Arab slave traders to be trained in hand to hand combat and sword fighting while memorizing the Quran an being bread for pure unflinching devotion to the Sultanate fighting in bloody battles across the Levant and yeah Chiesa looked like a total pussy in there.
For real though Holland should stay at WW, he's improved dramatically, I think it's less of a case with Chiesa being bad (although wtf was that awful telegraphed head ducking) and more to do with Holland improving his takedown defense and therefore shutting down all Chiesa has (grappling/wrestle fucking) and forcing him to compete in an area where he isn't even in the same dimension as Holland(striking).
Chiesa also seemingly aged somewhat I suppose but I'd give Holland all the credit here, he looked very good.
