Re: What will it take to make you feel better about this team?
There have been tons of highly successful mild-mannered coaches in the NFL.
Bill Walsh, George Seifert, Tom Landry, Joe Gibbs, Tony Dungy, Mike Tomlinson, to name a few.
There are still many today like Lovie Smith, Norv Turner, Leslie Frazier, etc.
Bill Belichik is also considered a mild-mannered guy, actually.
