Its 'pawing', but not in the way people usually mean pawing - its like a Lion pawing. It looks alittle bit like when guys sometimes turn around and fight southpaw and their jab sort of looks like theyre trying to throw a power punch
But...it's pretty effective. He used to very god effect against RJJ in order to establish punching range, and to throw Tarver off of his rythm in their first fight. Looks funny, but can't argue with the fact that it works.
