The Dallas Cowboys’ hiring of new head coach Brian Schottenheimer this offseason has already become old news in the fast-paced NFL world. With the start of training camp, fans and the media are getting to know the rest of the new staff, which includes defensive coordinator Matt Eberflus. Eberflus spent the last three seasons as the head coach of the Chicago Bears, but things were not going in the right direction last year, causing the team to let him go before the end of the season.
