For once the rumors have already begun as to who could be headlining next years class and that is Dave Batista. Though we haven't seen Dave inside a WWE ring since 2014 when he walked away from the company following a feud between Evolution and The Shield. Most people remember Dave's last night with the company because it was the same night that The Shield broke up and Seth Rollins turned heel. Once Dave left the WWE the last time his acting career actually began to take off and is slowly becoming one of the top up and comers in Hollywood with his part in the Guardians of the Galaxy series.
For those who may not be aware Dave began in the WWE with John Cena & Orton in 2002 as a deacon. By 2006, Dave would be one of the top names in the WWE and basically Smackdown's answer to John Cena. Even though he may not be on The Rock's level he would follow his lead in 2010 when he walked away from the WWE and would end up in Hollywood. With his developing name in the big city it would give the WWE a big name to build the 2018 class around. Now things can change between now and the ceremony but I do think it's pretty possible that Dave Batista will be the headliner for the WWE 2018 Hall of Fame class.
