I know closed fists are out of the equation, but what about a standard thumb to the eye? Edge isn't Ric Flair by any means, yet I've seen Flair thumb someone's eye then chop block them to weaken the legs for the figure 4. Well, Edges submission manoeuvre also requires him to weaken the legs so what's to stop Edge employing this same tactic on The Dragon? It could be that Edge goes down this route simply to make Dragon use up his rope breaks then go back to the spear.
As Sanka pointed out, the 20 count seems like it could be a saving grace for Edge; whether he uses the time to hurt Dragon outside the ring or simply to frustrate him and make him come and get Edge.
Admittedly I don't know too much about Ricky, but Sankas post gave me food for thought.
Edge isn't as smart of a wrestler. He frequently survived matches due to outside interference in one way or another instead of any abilities he may have had. Steamboat, on the other hand, would wear down his opponents frequently counter just about anything they would throw at him.
As for the thumb to the eye, anything that would be a DNQ would be treated the same was as a closed fist in Pure Rules matches in ROH, so I'm treating it the same way here.
