I see your point but what about his early push against the likes of Batista, Taker, Jeff Hardy? All those world titles and main events? Didnt he "retire" Jeff hardy in 09, thats huge.
In my opinion, Anyone else in Punk's place with the 6 yrs of push would have been a solid reliable draw by now, for the company.
Punk probably would've been, but for every really good thing Punk has had, it's been screwed up.
His first WHC? He wasn't quite at that level yet, and it ended in a poor way.
His second WHC/Jeff Hardy feud? It was all going good, and great for him he ended Hardy's career but Punk got himself buried by Taker with some remarks behind the scenes (not sure if ever confirmed though) and this probably would've been the run to cement Punk had that not happened.
The SES/New Nexus? Both led to nothing because they were treated as such. Mysterio handled SES and shaved Punk's head, and then Show comes in and dismantles them. New Nexus? Same thing and it got destroyed by Cena, and then Orton. Not to mention Nexus was a dead group by the time he began to lead it.
His shoot promo/Summer of Punk 2011? Comes back early, has an uneventful feud with HHH, loses, and then the night after he apologizes to HHH and becomes a squeaky clean babyface. He turns from an edgy babyface to a cringe-worthy jokester, much like Cena and now Sheamus.
His 300+ day title reign? He's been overshadowed by Cena constantly and has only main evented 2 PPV's. Sure, Cena main eventing with Rock and Lesnar makes sense. Hell, I even understand somewhat Cena/Laurinaitis main eventing over Punk's match (not like we could see the future and how much of a classic match Punk/Bryan was going to be). Also I suppose Cena ending MITB would be alright if it wasn't for the fact the MITB has never ended the PPV before. But Cena/Kane's ambulance match main eventing EC? Cena/Show main eventing NWO? Absolutely no reason they couldn't have at least put Punk's feuds/matches at that time on that level and main eventing Raw half the time. But they proceed to make him an afterthought.
Punk's Raw 1000 heel turn? He goes from a face who takes on all comers, had been in a couple triple threat title matches, one of which being a TLC, and having a lot of respect to all of a sudden having no respect, having a big issue with triple threats and becoming your standard cowardly heel number 156 who outside of his Summerslam match always gets out-smarted and made to look weak. There's nothing interesting about him as a heel besides the fact he's aligned with Heyman. The problem is Punk doesn't need a mouthpiece and it just feels like filler for Heyman until Lesnar comes back.
So while Punk has been graced with a lot of opportunities, he's been fucked out of more than his fair share. Now the first one I mentioned wasn't really anybody's fault, and though his reign ended poorly, he wasn't really ready for being the champion of Raw yet. And his second run his attitude cost him big time as that was probably the run that would've put Punk over as the top heel of WWE. However the crap that happened with his factions, the Summer of Punk, his title run and his heel turn that has been unspectacular is pure terrible booking and not his fault.
And ultimately it's that that's the reason he's not as big of a draw as he should be. He doesn't have the "it" factor where he can draw when doing nothing/having his feuds/runs/storylines ruined. I know a few people claim him to be the next Austin, and hell when he first did that shoot promo and for the first month, I thought the same thing. But it's clear now he can't ever be that. Could he be, say, an HBK? A HHH? Possibly, but at this point with his luck, it's very unlikely. He's certainly not going to be the face of the company, as he's just much more natural as a heel.
I would quibble with one point there, Starbuck, which is that looking over live events numbers, I think Punk during his babyface run in the last twelve months did have a positive impact there for the Raw brand and for Smackdown shows that boasted him appearing. At the Oakland, CA house show I attended back in January, there were literally thousands of fans wearing Punk shirts and who fell outside the Cena "net" of fans (i.e., kids and families, of which there were many, too). I think it's fair to estimate that Punk has made a bit of a dent in attendance figures for WWE, because Smackdown shows with him and no Cena have on average largely did at least decently above the average Smackdown show which only featured Orton or Sheamus or both. As one "Is Punk a draw?" thread concerning live events attendance went a few months ago, I remember a few people and I clarifying that while Punk isn't WWE's biggest full-time draw by any means, he is a draw. There's unmistakably a solid number of fans (many of them young adult males for whom Cena became something of a non-factor or potentially even a negative years and years ago) who are going to shows to see him above anyone else, and the numbers do bear that out. It'll be interesting to see what happens with him going heel, though I imagine a significant portion of those adult males will still be cheering for Punk, buying his shirts and going to live events chiefly to see him, lol.
Edit: Interesting. Never heard anything about live event numbers for Punk.
