Like it or not, Reigns is booked to be a strong ass mofo as well. It's funny how no one bats an eyelash to Brock no-selling a FINISHER, but Reigns seizes an opportunity after a couple chair shots and everyone goes ape.
You could book Curtis Axel to be a strong ass mofo as well. Doesn't mean the crowd would accept it. You have to build a guy up well to be at that point. WWE has not done that.
