One day Kei will be either vulture or overrated mug. Either player who won a lot in weak era or slamless pusher, so on. It`s like this site works it seems to me.
Though I`m surprised that no Djoko fan is pissed with him - Kei dared to beat Nole and then easily lost to Fed once.
He will never be a vulture because he will not schedule tons of 250/500 tournaments with weak fields to inflate his ranking. Nor will he ever be a Slamless pusher because he's not a pusher
