While I think that Foley doing certain things defeats the point of wrestling and shows how limited he could be, if he was just a glorified stunt man then WWE wouldn't have used him to solidify Steve Austin & Triple H as legit main event players.
Foley was used in Austin's first WWE Championship feud and people started to take Triple H seriously once Foley made him look like a star.
Great talker, plenty of classic matches, consistent performer, great gimmicks (all of them), he's probably underrated.
