I`ve always fought a high guard was difficult to get through specifically after watching Winky Wright, then I saw a film study on GGG showing how he can pierce through the guard and I wondered whether he is the best in history at that, Nunn couldn`t get through Starling`s guard much when he defended his middleweight title vs Marlon and he wa great offensively in terms of reach and handspeed, so I wondered which fighters in history dismantled tight high guards in the past, even Ali didn`t catch Tirrell that much in the what`s my name bout, so can anyone inform me? Thanks.
