I think with Grossman back the Bears offense will be considerably better.
He has what, 5 games worth of NFL experience now? I wouldn't bet on the offense being considerably better. Better, just not considerably better, IMHO.
Don't get me wrong, I'd love to see the bears win it all and have their defense destroy everyone in their way.
Since my team is out of it now, I'm pulling for the bears. Sorry, but that is usually the kiss of death for any team ;)
