At the end of the day, Wanderlei isn't about winning or losing, or trying to keep a good record or be known as the best fighter in the world. The man just wants to put on a good show and throw down, which is why we all love him.
The question that needs to be asked is 'would I rather see him throw hands with top guys in the UFC, or lesser competition in Japan?'.
For me, the answer is simple, I want to see Wanderlei break his hands and face fighting top guys that you know will give a good show, not scrubs(not that I have anything against Scrubs, Scrubs is awesome).
