With the revelation that Mularkey couldn't find assistant coaches, and that the criticism deeply affected him and his family, although I feel bad for him, it was only a good thing for the Bills that he resigned. A head coach cannot take criticism like that to heart too much, to the point of it making him want to quit. That's not who the Bills want or need as a HC. Also had he stayed, it's likely the Bills would have had to settle for some lame assistant coaches instead of the good ones that are out there. Would that have pleased anyone? I'm just glad I'm finding this out NOW instead of later, if at all.
Now hopefully the Bills can find some good assistants and a HC. I think they have a good chance of that.
