As long as nobody on the team gets injured you win in the preseason. Giants lost a starting defender for the season, the Bears lost nobody (that I've heard).
Other than that whatever, Bears looked awful last preseason (went 0-4 right?) and still managed to put together a playoff team. If it took you the NFL preseason to realize Roy Williams sucks, the Bears have a bad OL or that Chester Taylor isn't very good you haven't been paying attention. This preseason s*** doesn't matter and hopefully it will go away or get cut down to 2 games.
