That would be the JLA run that had to deal with things like "Electric Boogaloo Superman", swiftly followed by "Oh wait, no he's not"?
As I said, peaks and troughs, it's unfortunate that McDuffie is in charge at the time of Final Crisis, but it's not like THAT wasn't signposted and he couldn't have been unaware that the big three (and J'onn) would play a part of it.
