I'll play devil's advocate. You job is to hire the best coach you can. There's a coach with Hall of fame credentials available that has shown some problematic issues in the past. When you talk to him he's able to address how he intends to change those previous behaviours and that he's learned the errors of his ways. That's pretty tempting if you are a GM especially if other options are someone unproven or proven to be incapable of winning.
Not saying that I'd hire Babs if it was my job, but I can see how it happened.
