Is Edge known friends with Dave? I get that he thinks Edge is a great wrestler and should get in because of that, but there's literally nothing else that makes Edge stand out. He was never a draw (aside from a whopping two weeks ratings jump when he first became champ), was never really over as a face until his last turn and his manager or valet almost always got more heel heat than he did. While he was never a "handpicked guy" like an Orton or Batista, he certainly was someone the company pushed and pushed until he was accepted as a main event guy through sheer attrition.
Speaking of Batista, it's amusing to see him drop off the ballot while Edge remains. While Edge was the superior wrestler (I guess), Batista at least could be considered a strong draw. He had the Wrestlemania against Triple H as a definite feather in his cap and has been noted to have increased attendance during his first reign. Edge, who has been touted as carrying the Smackdown brand, also had the Undertaker and Batista to assist him while Batista had to deal with Kane, Khali and post 04 JBL. I don't think either of them should be in the HOF, mind you, but I'd definitely close the gap if not eliminate both of them.
(As an aside, Dave pointed out on the WON radio show that Randy was looked at as the star of the Rated RKO team. Despite Orton wearing a version of Edge's entrance gear, being one to do the job in almost every match during their break up and being pinned clean in their blow off match. Okay.)
