Goldberg is not a draw according to buyrates. What is required of Main Eventers and Midcarders are two different things?
The current main eventers aren't draws, and haven't been since Wrestlemania X-8. Goldberg and the McMahon's aren't the collosal failures that Nash & Orton are, but they aren't doing much either. I'm not saying Benoit and company are either, but they might be. Push the guy who might succeed, rather than the guy who you know will fail.
What these numbers do show, is who in the midcard are the guys you want to push (ex. Shelton Benjamin) and those who you don't (ex. Rodney Mack).
