buggy is the first pirate to be beaten by the straw hat crew (when they were just luffy and zorro) so i could see how he is considered too weak to be a shichibukai. but we all know he couldn't lose to Mihawk! (until we learn if he has haki)

and coby being Luffy's rival could be a final scene in one piece. just think how the two people who became friends in the first chapter are rivals in the last chapter would be a fun fight to see.
