He only went up/down in weight once, and that was 7 pounds. At least Roy was coming down from HW to LW.
The thing that people are not recognising is that that was a devastating punch. Just the mere sound of it was stunning - reminded Lennox against Rahman. Absolutely no version of Dawson takes that punch well.
What a better version of Dawson does is be more alert to it. Adonis had already tried that same punch twice and just missed. Normally, a big KO shocks me. When I saw Adonis just miss and the way Chad was fighting, I felt it was coming. It did't surprise me.
But again, I will say - that was an amazing punch. That's kinda been lost in the discussions which have centred on Dawson's failings and wasted talent.
