Jones will rush all over them, but he won't get into the endzone because... and we all knew it was coming... GROSSMAN WON'T GET HIM THERE! I'll go with Chicago if Griese starts, but even then just by a slim margin. GB, by at least one TD.
Being a Packers fan in Chicago, I get even more analysis of the Bears team than I do GB, and I *like* Grossman, don't get me wrong, but he can't do a damn thing under pressure.
Will the Da Bearsss D stop #4 to a point, and therefore limit his production? Hell yeah. But they won't stop the Pack from getting to a point where the Bears will have to pass (from behind, or otherwise), the pressure will come, and Grossman will collapse like he always does.
Side-note : Playing the GB D in week one would be a real stretch, but in a deep league that doesn't count "yards against" against a D that you play, they really might not be that bad of a WW pickup. With Chicago's pitiful red-zone performance, if they even get there,
you could get a pretty nice performance out of them.
