#4 The Legitimiser

The main reason why fans do not like Brock Lesnar in any of WWE's main narratives is due to the fact that the former World Champion is never really around to hype up his feuds at the most crucial times. But if the rumors are declared true, then we could be seeing the best of Brock Lesnar in the next few months.
Rumors have stated that WWE is looking to draft Lesnar to SmackDown Live, as WWE's deal with FOX will see them try and make the blue brand a more sports orientated programme, and what better way to do this than having the UFC centric Lesnar on the brand.

Lesnar could thrive in this environment as he doesn't really need to be on the brand full time if he is inclined in one-time feuds. Therefore this could be a shocking moment that sees the blue brand end up being the hottest brand in WWE with stars like Lesnar on the roster.
#5 The Club reunites

We spoke earlier about the possibilities of WWE bringing the IC Champion over to SmackDown Live and sending the US Champion in the other direction, so, with the possibility of witnessing Finn Balor on the blue brand, could we see him reunite with his former worldwide acclaimed faction?
If WWE does the shocking thing of keeping AJ Styles on SmackDown Live, it would be logical that we see the company create a Bullet Club centric narrative around The Good Brothers, Styles, and Balor. This would also be the best way for WWE to rebuild Balor's broken career, as anyone that works with Styles progresses to the next level.
