#2. Ric Flair

Ric Flair is Widely regarded as the greatest professional wrestler of all time in a career that spanned 40 years. He is the only two-time WWE Hall of Fame inductee, first inducted in 2008 for his individual career and again in 2012 as a member of The Four Horsemen. "The Nature Boy" had a memorable retirement match with Shawn Michaels at Wrestlemania 24 that was lauded by fans and critics and was voted the 2008 Pro Wrestling Illustrated (PWI) Match of the Year.
Flair most recently returned to congratulate his daughter, after she won the SmackDown Women's title from Natalya, ironically in Charlotte's hometown of Charlotte, North Carolina, this being his first appearance for WWE since nearly dying earlier in the year when he went into a medically induced coma.

With Wrestlemania season already looming, Flair would be a great addition to the show as a host. The "limousine-riding', jet-flying', kiss stealin', wheelin' dealin', son-of-a-gun" would make Wrestlemania 34 a memorable event. Inviting everyone to Wrestlemania to a roar of "wooooo!" would truly be a moment to remember.
