Bears Should Fire Lovie
I know this may shock some people, but that is the only conclusion one can come to given another drubbing where the team could make no real adjustments. This season has been an utter disappointment and it follows on the last two years of disappointing .500 ball.
I certainly don't think it is all on the head coach. Just like the last two years, the offensive and defensive lines have been mauled by opponents and it has killed them. However, you still have to play and scheme. The Bears make the same mistakes week in and week out. The defensive tackles and defensive ends are not disciplined with their gap and contain responsibilities. The linebackers don't drop into their zones. The secondary plays too loose on third and long plays and they get whipped on D.
On offense, their O-line is a disaster. Pace is far past his prime. Their LG has been a problem all year. Chris Williams has been disappointing playing out of position at RT and their two holdovers from last year - Kreutz and Garza - are consistently outplayed. It all starts from there - the Bears cannot mount a running game or allow enough pass protection to effectively use Forte and Cutler. I think Cutler still makes too many bad decisions and the receivers are inexperienced and make some mistakes, but those can be overcome with a better O-line.
Lovie is the D-coordinator and he hasn't held the offensive coaches responsible in any discernable way for the way the O is playing. Three years out of the playoffs is enough. I didn't think Lovie needed to go just a few weeks back, but it is pretty clear that the team is not playing for him anymore. At that point, you need to think about change.
