Sean Payton was the play-caller in Dallas. Those plays were obviously influenced by the Tuna, so it is hard to tell how conservative he really is philosophically. Because the Cowboys don't allow anyone but Bill Parcells or Jerry Jones to talk to the media, not much is know about his personality,etc. He was smart enough to turn down the Raider's job a couple years back though.
BTW, Nice to call Honda to your thread which no one responded to.
