No wait! How come Garp had a chance against the guy then, given that garp fights with his (blunt, most importantly) fists? I know about Haki, but given that there is a "King's colour" of Haki, I am led to beleive that Roger had haki as well. When both parties use haki the strongest wins, so Garp wouldn't even be able to touch Roger if he had the Gomu Gomu no mi.

Even allowing for Garp never being able to beat Roger thats a flaw, since Garp alledgedly came close many times.
