I will mention one fighter who fought well who was tall. Prince Charles Williams. You have to remember one thing, if a tall fighter fights on the inside a lot he probably does not have long arms. Hearns had a 78 inch reach which was long.
Prince Charles Williams was not tall for a Light heavy what was he 5-11 6-0? About average. First to come to mind Riddick Bowe,Genaro Hernandez. Jeff Fenech at 5-7 was tall at least when he was fighting at 118 and 122.
Riddick Bowe & Diego Corrales were the first two to come to mind. Bernard Hopkins was a pretty tall middleweight, and good at all ranges. Jeff Fenech was pretty tall for the divisions he fought at. Antonio Margarito can fight on the inside.
