#3 Kane
Another option that Bryan has, of course, is calling on an old ally to lend him a hand. Kane may be a Raw superstar, and busy with his new mayoral role, but I'm sure if the WWE really wanted to, they could convince to turn up for one night for nostalgia's sake.
Seeing Team Hell-No reunited would be a huge draw for the event, and it would also help give Bryan a serious boost before he heads into a match with The Miz at SummerSlam.
Of course, considering Kane's current situation, it is unlikely that the team would be victorious, but having The Miz cost them the match, and then brutalize Kane in front of Bryan could add even more drama to the duo's rivalry.
