#4. AJ Styles
2004 was, arguably, the peak of Chris Benoit's WWE career. That was the year he not only won the Royal Rumble, but went on to defeat both Triple H and Shawn Michaels at WrestleMania XX to win the World Heavyweight Championship. It never really got much better for him after that, career-wise.
AJ Styles, on the other hand, was still bouncing back and forth between TNA and Ring of Honor. The Phenomenal One was certainly impressive, even back then, but he wasn't even an echo of a blip on WWE's radar at the time. In fact, it was a little over ten years later before Styles even stepped foot in a WWE ring - much less become one of the company's biggest stars.
New Champs in WWE! More RIGHT HERE
So, let's play a little bit of the alternate history game, since this is essentially what this whole feature is about. Let's look at an alternate 2016, where Benoit is still in WWE and Styles is making his long-awaited debut.
Two of the best workers ever in their business, who never had the opportunity to step into the ring together (Benoit had left WCW a year before Styles would show up in the company) - that would have been something to see.
Could a 50-plus Benoit and a 40-plus Styles still have put on a match that talents of their calibur were capable of over the course of their careers? Well, it's impossible to say regarding Benoit, but even to this day, Styles seems capable of having a great match with just about anybody.
So, yeah. Probably.
