The Bears have a two game lead over the entire NFC and if Dallas beats NO sunday they have the tie breaker over any team that is two games behind allowing them to loose two games without dropping in the standings. Rex Grossman is the quarterback unless he has three turnovers that are definitely his fault in the first half of any game until they loose or, more likely, clinch homefield in the NFC. Lovie knows that this defence and special teams are the best in the leauge and can probably win any of their remaining regardless of the offence. Lovie has the luxury of allowing Rex at least two more games to prove he can still play. If Rex sucks the move to Griese will be made for the final two games of the season ensuring homefield in the NFC or just allowing Griese to work the rust off.
