Let me preface this by saying I'm a big fan of Jericho. He may be in my top five favorites of all-time. Rogers wins this, though.
As terrific a wrestler as Jericho is(was?), his main attribute may have been his charisma. He was incredible on the mic and had a great presence about him. He had some really big moments, and his WWF introduction was electric. Yet he still pales in comparison to the original "Nature Boy".
Rogers inspired the look and character of many wrestlers after him. For crissake, the guy who many think may be the most charismatic wrestler of all time, Ric Flair, ripped him off!
I do think that Jericho's undisputed World title win is one of wrestling's great achievements. You know what else was? Rogers winning the World title in what people were calling the match of the century, in front of a record crowd. Even when Jericho was champion, he always seemed to be overshadowed by Rock, Austin, HHH, etc. He wasn't booked to be the the number one guy. Rogers was. Jericho has a lot of spectacular moments, but he also loses a lot. Rogers rarely lost(other than Bruno.....), he was at the top of the card for a long time.
Jericho is among the best in-ring workers of his generation. Not only was Rogers a good worker, but he popularized the figure-four. That's a pretty big deal in wrestling history.
I could ramble on, but Lou Thesz said this:
Rogers is remembered by fans and performers alike as one of the top all-time stars in the business, but its probably not common knowledge just how influential he was
he broke into the business somewhere around 1941 as a hero-type personality, with little more going for him than a good body and natural charisma in the ring which is actually a pretty good beginning and he was a hit almost from the start. He had that indefinable something fans responded to, and he was sharp enough to build upon what he had, paying attention to what got a reaction from the fans. What evolved over several years was the Nature Boy, the prototype of the cocky, strutting, sneering, arrogant peroxide blond villain that is almost a tired wrestling cliché today. Rogers invented the character, and I believe he did it better than anyone.
He was also one of the first guys to rely a lot on what we called flying moves in the ring body slams, dropkicks, piledrivers, ricochets off the ropes into his opponent, action moves that are commonplace today. All of those moves were in use before Rogers came along, but they were used sparingly; most of the wrestling prior to Rogers emergence was done on the mat. Rogers was the first to use flying moves in quantity, staying off the mat, and the style was so popular with the fans that other wrestlers, including me, followed his lead."
Who am I to argue with Lou Thesz?
They both talk a lot of shit about each other, Jericho jumps his ass but Rogers wears him down and makes him tap to the figure-four.
