he wasn't demoted by Parcells because Parcells was already gone. Phillips was the coach by then and brought in his "own guys" (jerry Jones' guys, too). Sparano was a Parcells guy, Parcells brought him to Dallas, then brought him in to be the head coach in Miami. Sparano was only "demoted" because Phillips/Jones wanted Garrett, the former Cowboy. Sparano was not demoted because he couldn't call plays, Dallas scored 27 ppg his OC season. Don't get all your info from wikipedia or ESPN or wherever you got this.
Ok. I thought parcells was still there in 07. Makes sense phillips wanted his own guys.
