Patrick Mahomes feels he has not played his best football in the early stages of the season, despite the Kansas City Chiefs being 3-0 after Sunday's victory over the Atlanta Falcons.
The Chiefs – who are targeting a historic Super Bowl three-peat this term – opened their campaign with dramatic victories over the Baltimore Ravens and Cincinnati Bengals.
They were handed another stern test by the Falcons in Sunday's late game, relying on their defense to produce two big fourth-down stops in the closing minutes of a 22-17 win.
The Falcons, who impressively dispatched the Philadelphia Eagles in Week 2, had multiple chances to score a go-ahead touchdown, only for Kirk Cousins to throw a pair of incompletions in the end zone with just over four minutes to play.
Mahomes threw for 217 yards including touchdown passes to Rashee Rice and JuJu Smith-Schuster, though he also threw a pick to Justin Simmons, who now has six career interceptions against the three-time Super Bowl champion.
"I feel like I haven't played very well and that's not a stats thing," Mahomes said after the game.
"I just feel like I'm missing opportunities whenever they're out there and not throwing the ball in the exact spot I want it to be at.
"I'm not playing my best football and we're still getting wins, so I've got to get better to make the offense better."
Mahomes' 659 passing yards for the season ranks 10th among all quarterbacks, while his passer rating of 89.9 is just the 17th-best in the league.
Ahead of a challenging Week 4 visit to the Los Angeles Chargers, Mahomes is determined to step things up.
"It's about me getting back to my fundamentals, putting our guys in the right positions, and then we've got to execute at a higher level offensively," he said.
"If teams are going to make us drive the field, we have to prove that we're able to do that, and I'm sure we'll get a lot of the same this next week with the Chargers."
