I get his beef, if he really has beef, which I think he does. WWE always signs the big name back (Lesnar/Batista maybe Sting too) and they get thrown right into the title picture or a big story line. For guys like punk who do the house shows and all the other stuff related to the business, its probably a real kick in the nuts. You think you're going to get a big role and boom here comes Lesnar or Batista and they're bigger names so they go in front of you.
Too bad, because he's probably one of the best at what he does. Not many can work the mic like him or wrestle like him.
