^^^ Well they are "rookies". Maybe the logic suggests they don't feel accomplished enough to take on the top dogs, but taking on someone who is a stepping stone to where they want to be, plus Miz-Danielson has history to it and makes more sense than a rookie randomly showing up and taking a crack @ the world champ. The fans wouldn't buy into that in the least.
If your number 1 goal isn't to become World Champ of said company, what are you there for? They say they want to make a name, get people to talk, what better way than in your 1st ppv match, you go for the World Champ. Sure there maybe money in a Miz/Daniel feud/match, but logicly when given the oppertunity to challenge for a world title, you're an idoit for passing it up.
