Re: Whether you like him or not CM Punk is now carrying a lot of the company weight.
Yes. He is. With Cena gone on injury he is the top guy right now on house shows and the like.
However as for the ratings argument, he is not picking up the pieces left behind in the absence of Cena. He is in the only drawing segments of the show, however the ratings are still low, the people who watch a lot the show and wait for a Cena appearance don't do the same with Punk and usually switch out and in only for key things.
Anyway, the show is still a clusterfuck right now and has no direction outside of the main event feud(which is pretty fucked with Cena's injury now too)
