So him becoming the first european oyakata is just a publicity stunt? Or why else would they give a 34 year old gaijin a heya? Yes, he wasn't the greatest ozeki. But he got there in just 18 basho/3 years with only 1 MK on his way and held the title for almost 8 years (47 basho). And this single MK as komusubi was the only MK, which was not due to going kyujo.
From what i've read he wants to do things a little bit different, especially when it comes to training methods. And don't see only the physical aspects of thraining. How many hopefuls have failed, because the problem was in their heads and the rigid, traditional system destroyed them? He still is european, so his approach to coaching WILL be different. You can't completely forget a system that molded you for 19 years. Maybe leading a new path instead of following the beaten path is a way to success.
And listening to what other coaches (sports in general) say in front of the camera, i sometimes wonder if they need help tying their own shoes, but nevertheless they are highly successful. He has the hunger for it, he has the support and he has almost 31 years until retirement. His name alone will draw hopefuls, who want to join the new way.
