You can't take the two men out of the ring once the bell goes. From the beginning until the end the same two guys are in there. The idea that some fights are just a free for all brawl and that skill, resolve and fitness to explode into war are just attributes that anyone can employ kind of demeans all of the sport. I know that we all know it's more complicated than that but taking s fight out of context and getting all microscopic over it misses the point. The whole enterprise is a huge and pointless display of barbarity on one level and an artform on another. Marvin and Tommy condensed so much about life in that opening round though that even a complete noob would get it. That does not mean it is in itself a one dimensional experience or a shallow and vacuous piece of work that should be dismissed because there are more nuanced or similarly intense fights drawn out over 12 or 15 rounds. It is a breathtaking ride still, and deserves it well earned status.
