Those same qualities, with Bieniemy as offensive coordinator of the Kansas City Chiefs, have helped the Chiefs to a fast start despite having a first-year starting quarterback in Patrick Mahomes. The Chiefs are one of the NFL’s three 3-0 teams and are leading the league in scoring at more than 39 points per game.
Oh, and Mahomes has set an NFL record with 13 touchdown passes in the first three games of a season and leads the league in passer rating.
Reid calls the offensive plays while Bieniemy helps assemble the playbook and weekly game plans and runs the offensive meetings. He’s also the voice in Mahomes’ ear through the headset on game days relaying the playcalls.
Those aren’t jobs Reid would trust to just anyone.
"[Quarterback] is a detailed position," Reid said. "… It’s very easy to go, ‘Ah, we can let that one slide.’ That’s [not] how [Bieniemy] goes about it. He’s going to make sure everything is covered. I trust him for that. I can’t be there every second. He jumps in and just takes charge and I have full confidence in him so I can go be the head coach and he can run the offense. He does a heck of a job with it.
"When he brings it, he’s bringing it and it’s every day. He doesn’t let one thing slide. … This is him. It’s attention to detail and ‘I’m going to make sure my closet is clean and your closet better be clean, too. If not I’m going to help you clean it.’"
Bieniemy wasn’t the most skilled of players, but he lasted nine NFL seasons because of his mastery of the little things. Beyond his special-teams work, he developed into a reliable third-down back because he figured out defenses, coverages and blitzes.
He now transfers that knowledge to others.
"I take a lot of personal pride in making sure everything is dotted, T’s are crossed and everything is absolute," Bieniemy said.
Chiefs running back Spencer Ware gave Bieniemy credit for helping to resurrect his career in 2015 when he joined the Chiefs after being released by Seattle. Ware went on to lead the Chiefs in rushing in 2016.
"I think the biggest thing Coach Bieniemy [brings] to our offense is his intensity," Ware said. "If you take a look at his résumé and the players he’s coached and the way they play football each and every play they get out there on the field, having an entire offense with that same mentality is pretty exciting."
Mahomes, who has seemed unstoppable at times this season, sees Bieniemy’s game-plan preparation as a big factor.
