#2. WWE RAW Superstar R-Truth
R-Truth is an absolute wrestling veteran and has been with WWE since 2008. During that time he's wrestled against almost everybody walking through the doors of the company, but one man that he has never faced in singles action is The Tribal Chief Roman Reigns.
The pair have also only shared a ring together a total of ten times since they've both been with WWE. There have been three Royal Rumbles, three Battle Royales, one six-man tag team match, a handicap tag elimination and two normal tag team matches.

When you add to this the fact that R-Truth is a multi-multi-multi WWE 24/7 Champion and that not once did Roman Reigns even consider just quickly pinning him to win the title, you start to think the two might never face each other in singles action.
Currently there's absolutely no reason for R-Truth and Reigns to fight in WWE, but I'm sure there could be a whole host of creative ways to have the brooding and serious Head of the Table Reigns take on the silly and funny R-Truth.
