You mean the Summerslam headlined by Brock/HHH with Punk in the midcard? You crediting Punk with that?
Bryan/Orton at HIAC did 228,000 buys.. Higher than what Punk ever did at that same PPV.
Bryan/Orton at NOC did 196,000 buys.. Higher than what Punk did with HHH at his hottest point during the Summer of Punk (he did 169,000 buys)
Bryan/Cena at Summerslam did 311,000 buys.. Higher than what Punk/Cena did at Summerslam (they did 296,000 buys)
The only number Punk did better than Bryan was NOC 2012 but he only did that because he was working with Cena. Bryan at the same PPV did only 10,000 less with a shytty card and without Cena to work with.
Bryan also carried the entire fall with Cena on his back and ratings were higher than they were the previous year with Punk as champ. What happened the one week Cena went down in 2012 during Punk's reign? Oh yeah, a fukking 2.5 rating happened:

As for House Shows, Punk never even headlined his own tour! That just shows how much bigger Bryan is. Dude was headliniing his own tour and by March was selling out venues. Just look at Meltzer's reports.
