What's to rate? It was an all-time classic moment in wrestling. Everything came together perfectly and the execution was spot-on. If you were around for this and didn't get emotionally involved, one or another, then you're probably watching the wrong sport.
I saw it at the time and was totally shocked. I didn't see it coming and later labeled the turn a classic case of Dusty hot shotting something out of nowhere. More recently, I've been able to go back and see the hints of the turn that were dropped almost from the start of Barry and Luger teaming in early 1988. With that context in mind, this was an outstanding turn.
