Schottenheimer, who twice turned down head-coaching opportunities, finally landed a job after going 12 hiring cycles without an interview.

His first season as offensive coordinator in Dallas brought similar highs: the Cowboys led the league in scoring, ranked third in passing yards, and finished second on third downs, while Prescott concluded that season second in MVP voting, finishing with a career high in completions, passer rating, and a league leading 36 touchdown passes.

The Dallas Cowboys' offensive line projection is among the least controversial predictions on the roster, but that isn't shying head coach Brian Schottenheimer or offensive coordinator Klayton Adams - an O-line expert - away from experimenting with different formations at training camp.
