Y do you all want him to use a kick of some sort? I think there could be a few other sorts of finishing moves that would be effective, look appealling and would suit Jericho.
And he cant lose the Walls of Jericho or Liontamer - those moves are so well known, specially the Walls. I think this new finisher will replace more the Liontamer, than the Walls, if at all. This is ofcourse, his new move ISNT a submission move ...
