Patrick Mahomes said the Kansas City Chiefs were motivated in Sunday's crushing victory after the Las Vegas Raiders "disrespected" their logo pre-game.
The Chiefs showed no mercy in a 48-9 demolition of the visiting Raiders at Arrowhead Stadium, where Mahomes threw two touchdowns to help fuel the rout.
It came after the Raiders gathered on Kansas City's logo before the contest and Chiefs star Mahomes addressed the subject following the team's sixth successive victory.
"You definitely don't want people to come into your stadium and disrespect things that you kind of built,'' said Mahomes.
"It gave us a little more motivation to go out there and win against a really good football team that we have a rivalry against that usually is a tough football game.''
Raiders defensive end Yannick Ngakoue gathered his team-mates for a pre-game speech and Chiefs star Tyrann Mathieu added: "I don't think champions really act in that manner."
Las Vegas linebacker K.J. Wright conceded the Chiefs were right to feel annoyed.
"I would have been upset, too, if I was them," Wright said. "Anybody that comes there and do that? And they definitely came out and responded to their anger and we couldn't hold up.
"It was spur of the moment. One guy said, 'Let's go' and we all got to ride together. We all went out there together. We did it as a team and just gave them a little more motivation than we needed to give them."
For the Raiders, it was more of the same against the Chiefs, having become accustomed to losses in this game. They have won just three of 18 games in the rivalry since Andy Reid was appointed head coach of the Chiefs in 2013.
The Chiefs were also determined to continue their dominance against the Raiders, who took a victory lap around Kansas City's stadium last year, having trumped their rivals for the first time since 2012.
"We didn't want them winning here again," Mahomes said. "We went out there and handled business."
Mahomes completed 20 of 24 passes for 258 yards and two touchdowns in the rout – moving him third all-time in the most yards thrown by a Chiefs quarterback.
The former MVP was masterful, ending a two-game run without a TD pass by posting a season-best pass completion rate of 83.3 per cent. He stretched his record run to 20 consecutive regular season wins in QB starts in November or later.
