The undercard was complete dogshit, so they couldn't pad shows with shit that was moderately enjoyable.
Disesel got over as the badass heavy for Shawn Michaels, and as soon as Vince switched him babyface and put the title on him, he was doing an "aw shucks" vanilla babyface gimmick. It's literally what he did with Cena and Roman, because that's what Vince's idea for a top guy always was. Worked for Hogan, Backlund didn't have the charisma to pull that off specifically, and it worked for Cody. But Stone Cold is the only guy who got over outside that mold and let him continue being that guy.
