Cena did a 100,000 less overrun than Punk just a few weeks after 1000. But because the rating was above 3.0 it isn't considered all time low.
This third hour is such an anomaly that we can't put all the blame on any feature player for it. People just aren't willing to stay with the show that long and until I'm proven wrong on that it's gonna be the main problem. It's not like there's a Sting vs NWO angle going on that's enticing anyone to stay.
Punk talks like he's on that level. Like he's that kind of draw. Why not measure him up to NwO/Sting acts since he's "putting asses in seats" and all that kind of slick tomfoolery he loves to boast about? If it's good TV, the third hour inclusion wouldn't even matter. It would be like it used to be with the fans NOT GIVING A fukk about the 1st hour and tuning in for the usual format like they did all the time during the Raw 3 hour specials.
