Why doesn't Jericho do a legit Walls of Jericho anymore?

This has been covered but indeed it probably has to do with Y2J not being able to properly apply the move on bigger superstars!! If some people said it hurt a little too much i buy that it looked painful the original walls!! Why call it the walls its a damn boston crab. Almost an insult to the minds of the IWC faithful if they dont call it anything else other than the boston crab. Its all about keeping these guys safe and still trying to entertain!!
