#2 Roman Reigns vs Seth Rollins
The ultimate slap in the face to Jon Moxley, a feud between his shield brothers.
With their new wild card rule, Seth and Roman could have a proper feud and even main event a PPV. With this happening and Renee on commentary, this would be a huge shot at Moxley and AEW.
Obviously, Rollins and Reigns are still friends with Jon as are others on the roster, but with everything, WWE did for Moxley in his exit, such as him main eventing Fastlane and having his own network special to say goodbye, Vince will probably be extremely angry at him.
Doing this would also probably create some buzz as any type of shield feud is over with the fans and it would be more than ever now with Seth being a really over babyface and Roman being more over than ever. This could be a smart idea from WWE if they do go ahead and do it.
