#4 AJ Styles
No disrespect to Shinsuke Nakamura, but this is the real dream match. You can talk about Seth Rollins, Kenny Omega, and others, but AJ Styles for my money is the best wrestler on the planet. He's an incredible athlete and incredible storyteller in the ring. It's a shame he came to WWE two years after Punk quit.
The two have faced off before, but the last time was over 15 years ago at an IWC event. These two against each other in the prime of their careers would have been the main event of WrestleMania. It's hard to judge if they still could since Punk has been gone so long, but AJ can make just about anyone look good.
That United States title around Styles' waist, by the way, is the one title Punk needs to complete the grand slam. That could be the perfect program to bring Punk back into the company if they choose not to rush him to the top of the card.
Adding to the intrigue is the presence of Anderson and Gallows. Punk could recruit some help and elevate a couple of young guys in the process. It seems like the perfect opportunity for The Street Profits. I think the entire WWE Universe wants that smoke.
