#1 Claymore Kick is banned
This is definitely the most obvious Extreme Rules stipulation that Dolph Ziggler could add since the Claymore Kick has been Drew McIntyre's power since his return to the main roster.
Of course, Ziggler did promise that his stipulation for Extreme Rules would be one that had never been done before, and this has been done in the past. A few years ago when Seth Rollins took on Randy Orton inside a steel cage, the RKO was banned but Rollins used it on Orton to pick up the victory.
Hopefully, if this is the stipulation that Ziggler chooses then he finds a way to add his own spin to it so that it isn't as similar as it was back then.
It's likely that it won't be that both of their finishers are banned because Ziggler will want to be able to use his own, but if he bans McIntyre from doing the Claymore then he might decide to use it himself.
There are many ways that Dolph Ziggler can gain an advantage this weekend, hopefully the stipulation is the added twist that the Extreme Rules pay-per-view currently needs.
