#5 Dolph Ziggler and Drew McIntyre vs Seth Rollins and Dean Ambrose

Dolph Ziggler and Seth Rollins main evented Extreme Rules in an iron man match for the Intercontinental Championship. It was littered with falls throughout, but the decisive one came when Drew McIntyre distracted Rollins during the sudden death portion of the match. Ziggler barely escaped Pittsburgh with the title. But now, Rollins has more reason to go after Dolph and Drew. This has been a really compelling feud and it could be furthered. It has been established that Rollins could not this on his own.
Enter Dean Ambrose. The Lunatic Fringe got injured at the end of 2017 and was said to be out for about six to nine months. Summerslam perfectly coincides with the timeframe of Ambrose's return. He could be back to help his former Shield-brother, as he had been doing prior to his unfortunate injury. Anticipation for Ambrose's arrival is high, so the moment when he does make his return would be a big one. It could come during a two-on-one attack from Ziggler and McIntyre on Seth Rollins. The pop would be huge.
A tag team match would be an extremely fun way to utilize all four of these guys for the Summer Spectacle. It would provide some good quality wrestling, along with a nice way to close the book on this great feud. The Intercontinental Championship feels like the biggest title in WWE today, and it is thanks to performers like Ziggler and Rollins. But it might not need to be defended at Summerslam for the sake of this tag match. The reunited team of Rollins and Ambrose could pick up the win and we move on to the next chapter for all parties involved. Perhaps we could get that Dean Ambrose heel turn we so badly want after this match.
