#2 Ziggler wins via count out
For this scenario to happen, we can expect a short 5-8 minutes match. Maybe he's so exhausted that he wouldn't respond to the referee's 10-count, or maybe he'll pull out some cheap shot like a heel-ish persona.
If this match ended up this way, then it'll be bad booking. Firstly, their rivalry was forcefully extended by unfair finishes and controversial booking decisions. Ziggler and Rollins have fought many times, and their rivalry is being extended by Drew McIntyre's unfair involvement.
Although Ziggler will retain his title at the SummerSlam PPV, it would be the worst booking as their last match has to end in a count-out victory. If no fair decision as to who did come out victorious in this bout occurs, then both men would look foolish.
In order for Rollins to go on to bigger things, he needs to step away from the Intercontinental Title, and allow Ziggler retain it successfully.
