I made this point in an earlier thread how Triple H got squashed in his first Wrestlemania but had a better overall career than Ultimate Warrior. I think the same will happen to Bryan and Sheamus.
Not going to happen. Sheamus is not going to be a flash in the pan, he has a job for life with WWE. Warrior was unstable as hell and drove everybody crazy to the point where they even made a DVD just to bury his career.
I doubt Bryan is even going to win the WWE Championship (not the World Heavyweight Championship, the WWE Championship, the true show of WWE's faith in someone), let alone have a better career than a guy who could spend 20 minutes in a No Lock without tapping and still win.
As for Triple H, obviously not, but that's kind of a pointless question. How many people have 13 world titles? Hogan, Flair, Cena and Edge are the only people besides Triple H who have ever had more than 10. Better off asking how many people thought he'd be a multi time world champion, or even a world champion, period. The answer is still no, because at that point he was terrible and had done nothing to break out.
