Do you also think Greco and folkstyle wrestling are the same since everything in Greco is in folkstyle wrestling?1. Neither bjj or judo's history stems from pankration. 2. Prankration don't have the exact same techniques bjj or judo do.
Carlson bjj and kodokan judo study the exact same techniques. The exact same. They just have different names.
Plus the creation of bjj came directly from a kano judoka named Mitsuyo Maeda, who taught the Gracie's everything they know.
I'm not sure why you're attempting to fight me on something that is common knowledge. Traditional bjj is the same thing as traditional judo. The only difference between the two is one sport spends more time on the ground work and the other spends more time on the clinch work.
