KANSAS CITY, Mo. —

The Kansas City Chiefs know Sunday’s home opener against the Philadelphia Eagles carries more weight than a typical Week 2 matchup.

It’s a chance to measure themselves against the reigning Super Bowl champions,the same team that denied them a third straight Super Bowl championship last February.

Chiefs head coach Andy Reid said the familiarity between the franchises makes this week’s preparation unique.

“We know them, and they know us,” Reid said on Wednesday. “There are going to be wrinkles in there for both teams, but we’re pretty familiar with each other. They have a lot of guys coming back, and we have a lot of guys coming back, so you have that part of it.”

Quarterback Patrick Mahomes said he studied the Super Bowl loss several times, calling it a necessary step to improve.

“It’s more informational than emotional,” Mahomes said. “You’re going to have failures in this league. It’s about how you respond from those failures. For me, I’ve got to continue to push to be even better so that I don’t make those same mistakes whenever I get the opportunity again.”

While Reid downplayed any lasting strategic edge from the Super Bowl, Mahomes said the rematch is about raising the team’s level against a proven opponent.

“When you play the best of the best, you have to take your game to another level,” Mahomes said. “It’s not different in the sense of it being a Super Bowl rematch, but it is different in that you’re playing one of the best teams in football.”

Mahomes added that the environment at Arrowhead should leave little doubt about the intensity.

“If you’re playing your first game at Arrowhead against the reigning Super Bowl champions, there’s got to be some extra juice,” Mahomes said. “There’s no reason you should come out flat this game.”

Mahomes and Reid said after last Friday’s loss to Los Angeles that energy was lacking at the start of the game.

Kickoff is set for 3:25 p.m. Sunday at GEHA Field at Arrowhead Stadium.
