Weekly game probabilities for week 4 are now up at Sports on Earth. Probabilities are a blend of the pre-season team strength estimates with a strong dose of stats from weeks 1, 2 and 3.
Please remember that the projected scores are not to be taken terribly seriously. Do not bet the mortgage on them as they are not intended to graded against the spread. They are simply a "maximum-plausibility" estimate given respective team scoring tendencies.
