#3. The Miz and Morrison getting disqualified
The Miz and John Morrison are two of the best heels on Friday Night SmackDown and the company has been playing that up quite nicely in the lead up to Backlash. Not only is that evident by the return of their Dirt Sheet segment a few months ago, but also by how they resort to ridiculous tactics, like smashing up Braun Strowman's car.
It's almost like the company wants us to see The Miz and Morison slowly getting more and more bold with their actions. Maybe that will lead to them trying to sneak a steel chair past the referee and nail The Monster among men with it. Or, the company could go a more Ruthless Aggression Era route and have the duo knock Strowman out with some brass knuckles.
From distracting the referee while the other gets in a cheap shot, to trying to ambush him, there are a lot of ways to get disqualified at Backlash Keep in mind that this probably won't be the most beloved option of the bunch, but it would at least help both sides avoid a huge loss.
