Set-up something nasty, my ass. The moment he dodged and went for the guy who just missed, the second guy would have pummeled him to the ground. He wasn't going to win. Suppose the moron infront of him didn't react and the guy who was getting punched did dodge, what would he do? The guy is basically against him and his arm is above the victim's shoulder. So basically, he has to take a step back for him to do anything (and continuing the hopes that the guy infront is just a cardboard cut-out) and in that time, theres no reason the attacker wouldn't just roll with the movement and end up on the ground with him. From there who knows, since it would be 1 on 1 and the cardboard cut out would get knocked over by the wind.
