The bad calls do matter. The Colts could have lost yesterday and it could have affected their playoff chances.
The Packers can beat the Saints. The Saints are not as good as they were the last two years. They lost at home in the divisional round last year.
With Rodgers you always have a chance. IMO GB has as good a chance as anyone in the NFC reaching the SB. Seattle has the same problems on defense, Saints are without Brees, the Bucs are beatable as they just got smoked by the Saints.
