Ya I alwayts figured this was more about pushing R-Truth and less about de-pushing punk. I like R-truth a lot actually and I think he's paid enough dues to at least be at the current JoMo level, if not higher in the long run. And working with punk is definitely a step in the right direction for him.
As for the Road Dogg thing, it is pretty convenient that the ref they decided to feud him against was the brother of the Road Dogg, but we'll see. IMO it would be pretty unlikely at this point considering he's had some choice words for Triple H in the past but you obviously never know.
Punk will bounce back into the main event, he always does.
