Meh, I'm ok with it. Proven guy, I think he has it in him to be that demanding guy that can change the culture somewhat and strengthen this team mentally. That being said, I still don't believe this team can win consistently enough to compete for a championship with the way its set up with the Jones' basically dominating the headlines and ultimately setting the culture where the HC just doesn't have enough stroke.
Offensively, the Cowboys will be ok. His DC hire is of the utmost importance. He was hit or miss in GB with it, and this defense needs a major overhaul in talent and scheme.
