After a 14-18 record in his first two seasons, there should be serious discussion about whether or not Brad Childress should return to coach the Vikings for a third season. There's not an obvious answer: an argument could be made either way.
But it takes a serious lack of rational thought to blame Brad Childress for today's loss at Denver. Childress didn't make Chester Taylor fumble at the goal line, costing the team 3-7 points (and he didn't make Taylor fumble later, leading to a Denver score). Childress didn't make Troy Williamson drop what would have been a 72 yard touchdown catch, costing the team 7 points (and he didn't make Williamson drop a third down pass later, either). The Vikings were playing a winnable game on the road at a difficult stadium, and at times they were playing really well. The Vikings lost because of obvious bad mistakes by individual players: it's difficult to put a whole bunch of blame on a head coach for fumbles and dropped passes.
I know those Viking fans who pure and simple loathe Childress will see this loss as his fault. And if you convince me that Brad Childress made Chester Taylor lose two costly fumbles and that he also made Troy Williamson drop two very easy passes, I'll agree with you.
