Norv Turner would've been better.
What, and Wade Phillips is a great candidate? The guy's the defensive version of Turner, except Turner's playbook is better. And Turner, despite sucking as a head coach, still had the guts to tell Jerry Jones to not dictate his coaching staff to him. Phillips didn't, therefore Phillips gets hired.
Wade Phillips is not the head coach of the Dallas Cowboys. Jerry Jones is. That makes two jobs, head coach and owner, that Jerry Jones sucks at.
