While it is true he only got his big pushes because he was able to wife Steph, you still can't deny him his right to be a top superstar.
Dude had shit on lock and in a bad ass, fuck you kind of way. Shit was never corny. His matches were awesome. His gimmick is fucking top 5. His theme song, "My Time", is top 5. His title reigns were memorable. He made the EC.
Yeah, he buried talent. Yeah, he rode the wave. But who the fuck wouldn't? You can't tell me no one else would've done that.
There's a shit load of "he wouldn't be where he's at today if..."
Same can be said for Stone Cold. If he didn't drop that 3:16 shit, he wouldn't be as big. If his wife wouldn't have said "stone cold", he would've never been Stone Cold.
Dude is definitely a top superstar, an all time great, no doubt. He was able to take hold and properly do it, without fucking it up.
