This game will be interesting on a couple of levels. For starters, we have two former Bears on the roster in Villarial and Gandy (as I imagine you know). Also, I'm curious to see how Hutchinson does. I know he struggled some against the Colts, but that was on relatively short notice. He'll have had more reps in the offense for this game, but on the other hand, it's safe to say that the Bills' D is a bit stiffer than the Colts'. It should be a pretty good measuring stick for Bears fans, although a less than stellar performance shouldn't be interpreted as doom and gloom in Chicagoland - our D has a way of making many QBs look that way.
He'll get better week after week, but if he performs at an average level in this game then there might be reason for optimism along the shores of Lake Michigan. But it would be nice to see what Rex could do with a couple of injury-free seasons worth of experience. Part of me wonders if we'll ever know - I almost feel sorry for the guy.
Either way, both teams should get some good work. FWIW, the Bears have been my NFC fave since I saw a game at Soldier Field back in the 80's during a visit with my sister (she was a junior at UC).
