I believe in him as well. For those that want him gone - if you think he's worse than what's out there, who's out there that you think is better? Or are you just enamored with the idea of 'surely someone has to be better'.
Maybe see how the season ends before you pass judgement. He didn't forget how to coach. This was never supposed to be a deep playoff year, so why are you holding them to that standard?
When you have holes in your roster and kids and journeymen starting - games like yesterday are going to happen. Dallas is a veteran team with a lot of talent at home and off the bye.
