Patrick Mahomes called for improvements and said the Kansas City Chiefs "expect greatness from each other" despite a record-setting victory over the Denver Broncos.
The Chiefs cruised past the Broncos 22-9 to collect a franchise record 12th straight victory over Denver, a streak dating back to Week 10 of 2015.
Kansas City also extended their winning run to five games on Sunday, despite quarterback Mahomes being far from his best.
The 26-year-old may have rushed for a touchdown on four carries, but he did not throw for a touchdown and was intercepted once on 15-of-29 passing for 184 yards.
Mahomes - who has already thrown 12 picks this season, as many as in his career-high 2018 campaign – was satisfied after yet another Chiefs win but called for improvements across the field.
"I think they know, from me and from all of us, and it's the same towards me as well, it's that they just have to be themselves," Mahomes told reporters.
"There's nothing they have to do extra. They have the talent, they have the playmaking ability to just continue to go out there and be themselves. I think we'll continue to get better and better.
"We're still winning football games. We don't want to get lost in that - we're winning a lot of football games, and we're winning by pretty big margins.
"But we expect greatness from each other. We want to continue to get better as an offense and the defense to continue to get better and hopefully create a great football team."
Mahomes has only thrown for more than 300 yards once in his past six games, while Kansas City have registered over 22 points just once at home this season against the Cleveland Browns.
In their previous five games, the Chiefs have allowed 17, seven, 14, nine and nine points, having given up 29, 36, 30, 30 and 38 in the team's opening five games.
They are the first franchise in NFL history to have a five-game winning run conceding 25-plus points and a five-game victorious streak allowing less than 20 points in the same season, per Stats Perform.
But 2018 MVP Mahomes insisted all the Chiefs are working on different ways to tighten up plays at both ends, despite Kansas City having an 8-4 record to top AFC West.
"You figure that when you get to, hopefully, the playoffs and kind of try to make a run that guys are going to try to take away those two guys," he added.
"We'll do our best job of still trying to get them open, scheming them open in different ways.
"But other guys are going to have to step up, and this week it was running backs out of the backfield. Next week, it might be other receivers, it might be different tight ends. I think we have the guys to do it, we just have to continue to go out there and do it."
