If we're talking trained folks, the usual suspects have been named. If we're talking legitimate tough guys/with the shyts when it's time to be about the action, then Jericho and Booker T immediately come to mind. I've read Sin Cara ain't one to fukk with either, and I assume Baron Corbin could hold his own.
The way Jimmy Uso slapped fire from Miz's face after he tried to put Naomi on that casting couch tells me that if you step on the right trigger, he'll fukk somebody's shyt up. Of the two Usos, Jey LOOKS like he has the better hands but I'm unsure if he actually does.
