How long has he been the only player with one belt? Just having one belt might not be legend worthy, but being the only player with it... for years... is different. Maybe not enough, and apparently the anonymous council has already ruled against it before.

In his own post he seems to have an ironic appreciation for the arguments against his being legend, that just being a cool player with a positive attitude, etc... isn't enough. Or I'm reading into it too much and he unironically does think that's enough reason to make him legend.
