#1 A win over The Rock cements Roman Reigns' place as the biggest heel in WWE

Roman Reigns is currently one of the finest heels in the professional wrestling world and it has only been a matter of weeks since he decided to drop his babyface moniker for good.
Within the next six months or so, Roman Reigns is only going to grow further as a heel, as he continues to dominate on the blue brand of Friday Night SmackDown.
However, if WWE hopes to cement The Tribal Chief's place as the biggest heel in WWE and possibly in the industry, he would have to put away one of the biggest babyfaces of all time in the form of The Rock.
While Roman Reigns continues to run the show on SmackDown and contribute in a major way to WWE, he wouldn't appreciate The Rock deciding to return after all these years and possibly taking the Universal Title off of him.
A win over The Great One at The Grandest Stage of Them All would certainly cement Roman Reigns' place as the biggest villain in modern WWE.
