The Kelly Kelly/Miz/Balls Mahoney storyline has been entirely booked by Dusty Rhodes. He’s very hands on when it comes to this storyline as he is laying out everything in it. Rhodes came up with the storyline a few months ago, then pitched it to Stephanie, and she gave her approval for it. Both Rhodes and Vince have worked hard on coaching Kelly Kelly on her reactions in the angle, and the feeling is that she’s made major progress as a character due to the angle. Other WWE writers haven’t interfered in the progress of the angle because ECW storylines sometimes fall below the radar, and thus no one has bothered to come in and tweak it to their liking. Furthermore, Rhodes already knows where the storyline is heading because he has the entire angle booked with a start, middle and a finish. He actually did that in advance. This is different from the norm because WWE storylines are usually booked on a week-to-week basis.
Raw writers Brian Gewirtz and Ed Koskey find Hacksaw Jim Duggan to be useful as a comedy figure, and that explains why they keep him on the roster. Although, it probably helps that he always gets a good reception from the crowd as well.
