A list of potential candidates to replace Mike Zimmer as Vikings head coach:
Kellen Moore, Cowboys offensive coordinator
Moore, 33, wasn't much of a quarterback with the Lions and Cowboys, but he's certainly a rising star in the NFL's coaching ranks. In his fourth season as a Dallas assistant and third year as offensive coordinator, the 12-5 Cowboys led the league in scoring (31.2) and yards (407.0).
And, yes, Moore calls the plays. Head coach Mike McCarthy was so impressed by Moore's run/pass balance and creative offensive mind that he kept him as offensive coordinator when he replaced Jason Garrett before last season.
Eric Bieniemy, Chiefs offensive coordinator
The former Vikings running backs coach under Brad Childress is now 52 years old and long overdue for an opportunity to use what he's learned from Andy Reid's tree of football knowledge the past nine years.
No, Bieniemy doesn't call the plays. Reid does. But Doug Pederson didn't call plays for Reid, and he went on to win a Super Bowl with the Eagles. John Harbaugh also went on to win a Super Bowl with Baltimore after serving as Reid's special teams coach in Philadelphia.
Bieniemy has been a creative game-planning influence. In Year 1 with Bieniemy as coordinator, Patrick Mahomes was the MVP, throwing for 50 touchdowns and 5,097 yards, and went 12-4. In Year 2, the Chiefs won their first Super Bowl in a half-century. In Year 3, they made it back to the Super Bowl. This year, they went 12-5, won their sixth consecutive AFC West title and secured a No. 2 seed.
