There is such a marked difference in Naz with Brendan Ingle, and after they split. Although the Kelley fight went down well in the US (the last fight with Ingle), those in the UK who had followed his career from the early days were mightily worried, and it turned out to be the beginning of the end. As unconventional as Ingle's methods were, that style was the perfect vehicle for his natural attributes (lighning reflexes allowed him to get away with the hands-by-the-side defence, insane angles made the most of his undoubted power). Suarez and Steward took the edge of this style, and turned Naz into nothing more than a decent counterpuncher with a shit defence. As has been mentioned, the focus was all on his one punch power, and he got hit a lot more since he was planting his feet much more and was less mobile. I would say that the last 9 fights of his career (post Ingle, and Kelley) included the 6 worst performances of his career: Kelley, McCulloch, Soto, Sanchez, Barrera, Calvo.
I'd still have him in a top ten feather list though...
