#4 The Miz helps Kevin Owens even the odds

SummerSlam could be Kevin Owens’ last night in WWE if he loses against Shane McMahon. McMahon is bound to have backup somewhere close at hand in the form of Drew McIntyre and Elias. Three men might prove too much for Owens to overcome, but one man who could surprisingly come to KO’s aid is The Miz.
Miz and Shane have had their differences, and if Miz comes to Owens’ aid, he can finally get some comeuppance against 'The Best In The World'.

#3 Ember Moon wins the SmackDown Women’s Championship

At this point, it doesn’t look like there will be too many title changes at SummerSlam this year, at least if you’re going by the odds before the show.
One match in which WWE could surprise us with a title change is the SmackDown Women’s Championship bout between Bayley and Ember Moon. Bayley’s title run has been quite uneventful so far, and WWE could switch things up in the SmackDown Women’s Division by having Ember Moon win the belt.
