My guess is that he was arrogant and waited two weeks before seriously talking to people. Now that he has a PR Nightmare on his hands he will put the search into Over Drive.
Unfortunately, once you get spurned publicly, it makes it harder for the next person to say yes.
Fire Hart
No evidence to suggest it started any earlier than last weekend. It seems apparent to me that Hart was banking on keeping Dooley around for as long as possible and didn't want to find a new coach. And when he absolutely had to, he responded by sitting around for 2 weeks and then going after second tier guys.
I don't care if we get turned down by 20 top tier guys, at least try and make them serious offers. Hart has shown that he is unable or unwilling to go after top coaching talent. He needs to be fired as soon as possible.
