Ueshiba would get his ass kicked today. Different era and mindset...no cultural limitations and/or consequences.
Keep fooling yourselves,
Takeda, Ueshiba, Sagawa, Mochizuki.....all prided themselves on MMA. Were they alive..they would be more current than most everyone. They would pursue modern combatives...and still have IP/ aiki.
I think it is a case of armchair athletes who so easily dismiss these men; what they did and what they accomplished.
I am not considering the nonsense ueshiba did in his later years.
