Dolph wouldn't be taking an F5 silly. He would be whooping Brock's candy ass all over the WWE universe. He would put Brock to sleep with the Sleeper, thus cementing it as a legitimate finisher.
Brock would demand a rematch, stating it wasn't the hold that put him to sleep, he was just tired, and then Dolph would beat him in the rematch with a Super Kick, giving Dolph 3 legitimate finishers along with the Zig Zag, that would become more like a signature move than a finisher, and would only be used to finish lesser opponents.
