No doubt. There's a coorelation where people assume boxing=punching. But boxing is a multi-faceted combination of movement. Arturo Gatti for example, was a great fighter, but he got completely outboxed by Floyd, right along with everyone else over the last 48 of Mayweather's bouts.
Manny was a solid boxer in his own right, really refining himself from power puncher into complete boxer. But he's at the end of his rope. That JMM knockout was really the breaking point, I think.
