#3 Samoa Joe gets involved in the match
When Joe arrived on Smackdown Live as part of the Superstar shakeup, fans started salivating at the possibilities that this would create. Who would he face? Who could he face? Nakamura, Styles, and Bryan are all men that he has had a history with at one point or another, the latter two outside WWE. While he may not immediately contend for the WWE championship, presumably he isn't too far from being in contention.
His arrival also came with a stern warning for the entire Smackdown Live roster that they had it easy because he wasn't there. One name he mentioned as someone he wanted to take out was Daniel Bryan. So given Bryan has a target on his back, we could ideally see a situation play out where Joe gets involved in the matchup. Whether it costs Big Cass (via DQ) or Bryan remains to be seen. However, Joe being around should serve as a reminder for Bryan to have eyes in the back of his head.
