Yey good call i was gonna mention him. Another one was Chicanito Hernandez although against Nelson he used his height to his advantage. See his fights with 2 short guys Jorge Paez and Harold Warren, he made those fights harder than he had too. Paul Williams is another one.
Diego Corrales was the first to come to mind. Riddick Bowe could be effective from the outside at times but was better on the inside IMO. Jeff Fenech was pretty tall for his divisions and liked to fight up close in the trenches. Paul Williams doesn't really know how to properly use his height and dimensions. While he did a lot of holding on the inside against Antonio Margarito (another tall fighter who can "fight short") I've seen him do good work up close as well.
Yesterday and today, I was yet again watching Terrell bore in and pummel Foster's body. Their match is compulsory viewing for anybody interested in this question.
Paul Williams comes to mind. I've only seen the footage of Abe Simon against Joe Louis, but if that is how he fought normally I would have to include him as well.
