Chiefs assistant Andy Heck unheralded key for ever-changing offensive line: 'I've got the best job on this team'

HENDERSON, Nev. -- The Kansas City Chiefs will play their fourth Super Bowl in five seasons on Sunday against the San Francisco 49ers. One of the most remarkable feats of the run is that they've undergone significant changes on the offensive line each time.

In four Super Bowls, Patrick Mahomes has had four different left tackles.

After losing Super Bowl LV to the Tampa Bay Buccaneers, the Chiefs underwent an overhaul, bringing in the core interior trio of Joe Thuney, Creed Humphrey and Trey Smith while adding Orlando Brown on the outside. They replaced both tackles this past offseason, signing Jawaan Taylor and Donovan Smith in free agency.

It's impressive that in a league in which the best offensive lines are characterized by continuity, the Chiefs have been able to plug in new elements and keep chugging along.

The man the offensive line credits most: Andy Heck, Andy Heck and also ... Andy Heck.

Unprompted during Super Bowl week, the K.C. O-linemen have praised their offensive line coach for the confidence and knowledge he's bestowed on the entire group.

"Coach Heck is one of the best coaches in the game, for sure," Humphrey told NFL.com this week. "He does a great job teaching us things, installing different schemes, things like that. He just does a really good job with it. He's been around coach (Andy) Reid for so long, they have a great relationship, they know how to work well together. They've brought in the right guys, too. They've brought in a group that has created a good culture in the core group and then adding in new guys, that seems to be a seamless transition because of Heck."
