#7 Samoa Joe vs. AJ Styles
AJ Styles is set to walk out of Chicago with his championship intact. All signs point to it. Shinsuke Nakamura's non-title win over Styles a few weeks ago basically advertised that he wouldn't be successful in wresting the title from his rival. He will bow out of the race after Money in the Bank.
Samoa Joe has already positioned himself as the next challenger, and WWE would be crazy not to do this match.
Joe has been low-key one of the company's best performers this year, despite being out with an injury for several months.
Styles' reign has run its course, and there's no one better than Joe right now to take the title from him. It's a no-brainer to book this match for SummerSlam.
Joe also already has beef with Bryan, which would serve as a nice bridge into another rivalry once he becomes the champion, as the "Yes Man" certainly won't be out of the title picture forever, assuming he signs a new contract, of course.
