#1 Should happen: Daniel Bryan should be the unknown attacker of Roman Reigns
Similar to McIntyre, Roman Reigns is another big name who is still without a SummerSlam opponent. Though the Big Dog was supposed to announce his SummerSlam opponent on SmackDown Live last week, it didn't happen. A shocking attack took place as a massive steel structure fell on top of Roman Reigns. Fortunately, Reigns was unhurt after the incident.
It's not rocket science that the unknown attacker is likely to face Reigns at the Biggest Party of the Summer. Since Samoa Joe and Roman Reigns have already faced each other a few times, another match could be tedious for the fans at SummerSlam.
A new rumour is floating that Daniel Bryan is the possible mysterious attacker. If it turns out to be true, Bryan should reveal himself and make the match official on RAW. Bryan and Reigns are incredible performers and they could tear the house down.
