#3 Roman Reigns turns heel
One thing that WWE fans have been begging for in recent years is a Roman Reigns heel turn, as the audience hasn't every really been interested in seeing the ex-WWE Universal Champion in the good guy role.
If Vince McMahon wants to prove that he's still willing to go out on a limb and try something different, then this is the move to make. If done correctly, it could prove to the WWE fans that things are on the verge of changing for the good within the organization.
In the end, a Reigns heel turn, especially if he turns against someone like The Rock, could end up making him the biggest babyface star WWE has in the long-run.
One thing's for sure, a Roman Reigns heel turn would pique the interest of the fans who are frustrated with WWE, and it would convince them to give Monday Night Raw and SmackDown Live another chance.
