I guess this is a thing. (https://nypost.com/2024/05/05/sports/cowboys-micah-parsons-battles-sumo-wrestler-in-tokyo-video/) While I mostly think it's a stunt, I wonder if there's any actual application to winning in the trenches by studying sumo techniques.
I've said for years that offensive linemen should take Judo lessons.
Sumo training can help with balance, leverage, shifting the weight and power of the opponent.
Living in Japan, I used to watch some of the Sumo matches. Many times, the undersized guy won because of balance and leverage.
