Week 5 Preview Bills @ Chicago Bears

Alright Chicago is #1 in a lot of power rankings but.. they are in the NFC who seems destined to never win a Super Bowl again, also they are in the anemic NFC north with the Detroit lions packers and Minnesota who the Bills already beat.
Granted, Rex Grossman looks like well no other QB in bears recent history.. good. Furthermore, Urlacher and the Bears defense hasn't given up a pass TD and is overall nearly amazing. In reality, the bears have played 3 teams that are ranked 30th, 28th and 20th in ESPN's power rankings and played a Seahawks team sans the NFL MVP.
This begs the questions, are the Bears that good. The simple question.. Probably. Thusly, quite a few things need to occur for the Bills to pull off a "major" upset in Soldier Field. Mainly, the leagues leading rusher, Willis Mcgahee, needs to produce, and produce hugely, to the tune of 100 yards and a score, Losman not take dumb sacks and not turn the ball over, and the defense to force Grossman to make mistakes. With the Bears front 7 it will take a miracle for Willis to break 100 yards especially with Duke starting at guard so.. Losman will need statistics mirroring that of his game vs. the Jets.

Prediction: The defense or Special teams score the Bills have a chance
