It does matter what they put on their website because that's where they house their records! If it were a real record, it would be mentioned on there. I can't remember the last time anyone mentioned that Orton was the youngest World Champion in WWE history, but again, it wouldn't matter. Just like with New Day, he's record isn't for either of the World Titles being worn by Kevin Owens or AJ Styles. The youngest WWE World Champion is Brock Lesnar. I don't who's younger between Finn Balor and Kevin Owens. You don't have to do long reigns. SummerSlam would have been sufficient. They would have broken the real record of 334 days and beaten that to make a full year with the belts. No need to drag it out another four months.
