I get what you're saying but I appreciate those guys for what they do. Even from a statistical stadpoint, like you say, most would be lost. I like hearing the different opinions and projections, despite how biased or wrong they might be.
I think the disconnect is when people rely on them like they're gold. They give you a base idea that an averag joe wouldn't have but to base a pick on what they say is ridiculous.
I do like Mike Mayock though.
