#2. Set up Samoa Joe's WWE return
In the lead up the SummerSlam match between Seth Rollins and Dominik Mysterio, WWE has included several important components to the feud between the pair, among them teasing the possibility of a return for Samoa Joe.
Samoa Joe has been on commentary for some time now on Monday Night RAW. However, in the lead up to this match, he did have a moment for himself when he stepped up to Seth Rollins on a recent episode of RAW. In doing so, Joe teased a potential return. Additionally, the former United States Champion has had his fair share of confrontations with Dominik Mysterio, as well. During Joe's United States title feud with Rey Mysterio, the former did have quite an interesting exchange with the latter's son and with Seth Rollins currently running rampant on RAW, The Monday Night Messiah could play a huge role in leading to the return of Samoa Joe.
Both Joe and Rollins have also feuded in the past on WWE's main roster but things could be a lot different and a lot more interesting with the roles being reversed on this occasion.
