I don't like the current way of showing red zone success; scoring drives in total drives. I don't think a field goal should be a successful drive for the offense at least not a completely successful one. After all as a defense if they are in the red zone i'm happy if we limit them to a field goal.
So I propose something better. Lets call it Red Zone Success Ratio (I'm open to a better name)
RZSR = Points scored in redzone / (number of times team got in redzone x 7)
So essentially you have a perfect score if you score a touchdown every time you get into the red zone. Plus, if they get a two point conversion we can say the falcons put a 110% when they were in the redzone :)
