The brawl looked very disorganized and maybe its because of the editing (
Al Snow acting shocked after beating up TNA people) or because it seems like they did something similar to a Royal Rumble.
In a rumble a wrestler only knows to beat up certain people but doesn't know about the whole brawl/match. For example, Jarrett comes to stop just Dreamer and Dreamer stops but everyone else keeps fighting like nothing happened while ignoring him.
