There were some more details in the Wrestling Observer Newsletter on WWE’s new edict on leg slapping.
Dave Meltzer reported that the story going around is that a big wrestler did a leg slap sloppily on SmackDown and Vince McMahon’s first reaction was to ban the slaps.
The feeling is that this will be forgotten about soon, similar to how there was a brief time when McMahon wanted no wrestling during the commercial breaks. Meltzer also noted that some of the reactions from people in the company on the edict is that with all of the real problems in WWE, why is this the issue that McMahon is focusing on.
Many wrestlers from previous generations have been slapping their leg or stomping the ring mat to create sound during their matches so the leg slapping is not just something that is being done by the current talent. Shawn Michaels, for example, slapped his leg all of the time when he would hit his superkick finisher.
