Re: CM Punk 2008 WHC reign - good or bad?
Going by memory, I think he wasn't ready. It was the aura of a mid-carder holding the title, something like Jericho in 2001-2002, which is not a good thing.
They didn't let him go over any top-stars (unless JBL counts for one). He fought Batista a few times, and each time it ended by interference or something.
If Punk was ready for The Show, he would have beaten Batista, at least once.
Punk's 2009 reign, when he cashed in against Hardy, was much better. After that reign, he was a solid main-eventer.
