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

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.

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.
