Randy Orton vs. the Rock sounds like a great matchup, actually. A very interesting clash of characters, with the sadistic Viper going after the Great One... but I'd prefer Randy doing it as a heel, since as a face, it feels very awkward. I feel like if the two met as babyfaces, it'd be watered down into a respectful "LET'S SEE WHO THE BETTER WRESTLER IS!" type of contest that doesn't include the character clash because it doesn't rely on character that much, or at best, it'd be Randy acting heelish just for a moment, then proceeding normally with the feud.
To me, late-2000's Heel Randy vs. Rock is kind of like Bryan vs. Michaels or Stone Cold vs. Ric Flair: a very interesting match that never took place.
A cool spot I could see happening in that match is Rock going for The Peoples Elbow on Orton and just as Rock bounces off the ropes the second time, Orton quickly rises to his feet and hits the RKO on Rock.
The ship has sailed as far as this match is concerned. It should have happened at Wrestlemania 21 or very shortly afterwards when Orton was still the "legend killer" and on the rise to the top. WM21 would have been perfect since:
-It was in Hollywood, Rock's new "home."
-Orton was the Legend Killer at the time. What better legend to kill in Hollywood than The Rock himself?
-Both were 3rd generation superstars.
-Both were the youngest world champions in history at the time of their first world title win.
-Rock had cut an epic promo in July of 2004 against Orton that could have even been perceived as a subtle/not-so-subtle planting of the seeds for a match between them the very next year.
-They interacted with one another in the 3-on-2 handicap match at Wrestlemania XX, it's fitting that they would then clash one-on-one at the next year's Wrestlemania.
-Orton could brag to Rock about how he cleanly defeated his friend Mick Foley twice and would now do the same to him.
I wouldn't necessarily hate it, but I'd definitely have very very little interest in it. I like Orton here and there, but he's just not someone (for me) that measures up when it comes to those big matches you see when the part timers appear. Rock against Punk, Rock against Cena at 28, even if a Rock/Lesnar rematch ever happened, those all felt/feel big. They were the real deal you know. Orton just, I don't know, it just sounds boring to me and I see Rock on an entirely different level than him to the point the match just feels like a waste of time.
