>>14129270It's an unwritten rule of WWE going back to the Corporate Ministry storyline that WWE management, generally presented on-screen as the General Manager of Raw/Smackdown, can compel people to wrestle The Undertaker at any time for any reason. Non-kayfabe, WWE understood that Taker had limitations that would prevent him from drawing on some long championship run, drawing better when presented as an opponent to other wrestlers. Since Taker had great matches with everyone, establishing him as an obstacle that random wrestlers could be thrown at created value in the card, and over the years it built a legend for Taker and helped tons of people get over.
