5 things that should not happen in Brock Lesnar's return to RAW

#4 Not adding the UFC angle to the storyline

Brock Lesnar and Daniel Cormier

The WWE acknowledged Lesnar's UFC confrontation with Daniel Cormier, and they have to add that to the storyline once again on RAW.

WWE needn't be worried about losing WWE fans to UFC or promoting a rival as there are several fans who follow WWE and UFC, including the UFC Heavyweight champion, Cormier.

Heyman talking proudly of his client's achievements in both the UFC and WWE ring and then putting down Reigns' ability would give the match the much-needed spice. He could perhaps even call-out Cormier! The crowd would love that, surely.
