The image is shown below and the text says "WADO-RYU founder Hironori Otsuka, now over 80, demonstrates block-and counter moves on Govender Krishna as Simbolon Edyson (left) and John Sullivan watch."
When it said John Sullivan and the Goju connection I thought, this isn't the Go Kan Ryu guy and luckily it isn't. That person is Robert Sullivan, phew.
I have enlarged that image slightly which is why it is pixelated but you can see the original on their web page.
The article includes the following paragraphs:
Hironori Otsuka, founder and chief instructor of wado-ryu, concentrates more on skull sessions, using the blackboard to explain a difficult point. In discussing energy, mass and motion, it seems he is conducting a class in physics rather than a session in karate.
But Otsuka is also strong on basics and kata, spending the first half of his training period having his charges practice straight punches and kicks, punch-kick combinations, blocks and counters, etc. Now more than 80 years old, Otsuka Sensei sometimes gets carried away in his huddle discussions, spending more time talking to the students and less time letting them train.
John Sullivan, who studied under Otsuka Sensei before coming to the college, complains about the lack of organization in wado-kai. He points out that there is no hombu dojo and that it is therefore difficult to take an examination for a higher rank.
