#2 Samoa Joe is being pushed again
Another huge possibility is that Samoa Joe is being pushed again. The former WWE United States Champion is one of the best wrestlers on the roster but has not been booked in the best way all the times.
However, ahead of WWE SummerSlam, now could finally be the time that Joe is receiving his push. An established talent with his heel abilities would make for some great moments in WWE. If this is true, the WWE Universe might have a long heel championship run to look forward to.
#1 To prove "anything can happen on the wildcard"
This feud might end up being nothing more than WWE's way of proving what they have been saying all along, that 'anything can happen on the wildcard'. WWE has been booking the wildcard as something that produces the most unexpected feuds.
This would be a very unexpected feud, and would also provide entertainment. It might just be their attempt at making the WWE Wildcard rule popular with the help of a feud that promises to be a good one.
