Sean Payton is in the market for a new offensive coordiantor for the first time since taking over the Denver Broncos, and all indications are that he will cast a wide net to find his next right-hand man. If Payton truly is willing to give up play-calling, the cast of potential hires is much deeper and likely more talented. Three external coaches the Broncos should consider for their offensive coordinator opening3) Kliff Kingsburry, Washington CommandersKingsbury and the Commanders parted ways after the regular season, and recent revelations suggest that Washington might not have been the best working environment this past season. 2) Klayton Adams, Dallas CowboysKlayton Adams impressed this year as the Cowboys' offensive coordinator, but has almost no path to calling plays in Dallas any time soon. After joining Payton's staff in a more senior role, he departed for Detroit to become their passing game coordinator under Dan Campbell.
