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.

Dallas Cowboys head coach Brian Schottenheimer is making sure his players remember the importance of discipline after a series of training camp skirmishes.

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.
