I think it's a little endearing that Foley is probably here because he's on so many ballots. He was on my 2016 ballot, even if not particularly high.
The thing with Foley is that he really, really got pro wrestling. He understood the imagination of fans in a way that only someone that is a fan himself could. I think he thought about things years before his time. He thought about "What's the one thing that could capture someone's imagination in this match?" in a way that people weren't really thinking, not in those terms at least. I think he was more "objective" driven than a lot of his peers who were great in other ways that were more based on anecdotal evidence and the legacy of doing things because they've always been done. If everyone around him did what worked, he thought about what might work.
Does that mean he's a top 20 wrestler of all time? No, but I do think he's very special in his own way.
