Again, I disagree. Triple H's breakout moment was the Foley feud with the Rumble streetfight and No Way Out HiaC where he retired Mick.
Now, if they have pulled the swerve, had Triple H win at Mania and establish a win over Rock and then go on to actually have a longer title reign, then okay, there's an argument there, but that's not what happened. After WM he immediately lost the strap to Rock at the next PPV and then they traded it back and forth for two more months.
Still though, the BIGGER problem is that Vince (and the McMahons in general) took center stage over both of them, which would become a recurring trend!
