Although I agree Brett Favre is one of the most overrated QB's of all time since some people think he is the best (not in my top 10), but no way he is the absolute most overrated. Gotta be a few more overrated than him.
What is Favre's record ATS for nationally televised games? I'm willing to bet it's very low and that's because the books adjust for Favre being overrated. More people will bet on him because they think he's good.
