I watched the game last night and here's my take on the Bears:
Defense will be good as long as they don't get killed with injuries like last year. The Cheifs scored on their 1st drive but once the D settled in, there wasn't anymore scoring until the 2nd and 3rd string came in. In the first pre-season game and 1st serries I'm not drawing any conclusions just yet.
On the other side of the ball, this will be the same old Bears team. Until Ron Turner is gone, the offense will be the most predictable in the league with a 2nd string QB throwing to below average recievers. Their new RB Forte is going to help and the rest of the committee can move the ball as well.
In conclusion, D will be better and the offense will suck again but will be better than last year without Benson back there. IMO, I would not play the over in every game just yet...
