Ricky Burns used it against Katsidis when he was on the ropes if I remember correctly. Was very effective because he has long arms and it covered his body too.
Have you read Atlas's autobiography? In it he states that a lot of trainers refused to work with Moorer because he made it a point of doing exactly the opposite of what the trainer wanted, and look how that turned out. I knew from the Holyfield-Moorer fight, that Moorer was not going to be anything special at hw.
Tho Wright was well past his best days I think even a peak Winky would struggle big time with Williams. Any doubters just watch the Soliman fight. Soliman a volume puncher not nearly half as good as Williams a stylistic nightmare for Wright.
I think Clottey is great. He's a very quick counter puncher with decent pop. His flaw is his competitiveness. He just doesn't really seem to care that much. The first 6 sounds of Margarito-Clottey are classic IMO.
