You beginning to see where I'm going with this?
Mr. Perfect's back injuries kept him out of relevancy at the worst possible time, just before he was due to get a second push towards the world championship. If he had been good to go, he could have had a sizable, multi-match feud with every one of these guys, and he would have put on a clinic. Perfect was 45 (or there-abouts) when he died in 2003, and the same age as HBK when he retired. His fitness was great, and even there at the very last he was able to do things like a perfect-plex against Big Show. From 1994-2004, there is really no reason without injuries that he couldn't have been involved with feuds with everyone on that list, and every one of them had the potential to be epic depending on the chemistry.
